Hello,
Does someone know how to really
cleana terminal? Not using thecleancommand which only put previous results out of the screen, but deleting them from the terminal. It's tedious when debugging with programs with long output not be sure you're looking at the latest attempt. I've seenresetbut id does nothing for me (mac OS)
@frank coral how doestput clearwork in macos?
tput is in ncurses-utils if it isn't installed by default

tput clear has the same effect as clear for me

@olive jungle sounds like you need to installpyqt5(or another Qt lib)
what OS/distro are you on?
olive jungle
@hollow venture Kali Linux
how do i install pyqt5 (or whatever lib works best here)?
hollow venture
You know how to install packages on kali?
If so, just install pyqt5
maybe apt install pyqt5 ? I haven't used it in ages, so not sure.

@olive jungle what do you get when you run this?
python3 -c 'import PyQt5'
@summer trail nothing

then PyQt5 is installed, and you're able to import it successfully.

how do i do that?

@olive jungle is this code being run in a vps ?

@crimson compass WSL
but i'm remoted in
so i have a desktop enviroment gui and so on
using rdp
using the xrdp service
crimson compass
Yes that's the issue there :)
If you run you script from a terminal within the rdp it should work
olive jungle
it does not work that way
i would only test a visualization tool within the rdp environment and nowhere else
crimson compass
Oh My! Then you have bigger issues :p
Didnt use WSL but I'm trying to understand
I'm sure its X related error

Run these two commands

crimson compass
Yes for the venv you can delete it and create it elsewhere
olive jungle
crimson compass
Do you have a requirements.txt in that folder ?
olive jungle
no

( otherwise we will get dependencies one by one )
Hhhh ok let's go than
pip install matplotlib
It would be easier if you share the import section w
Of the script
We will guess the required packages
olive jungle
i'm just a beginner but beginning is hard
crimson compass
And then you can put them in a txt file and name it requirements.txt
i'm just a beginner but beginning is hard
@olive jungle nah you're fine , keep going
( phone keyboard is laggy )
Always keep in mind to store the required packages in a single txt file

do i have to do this x16?

This is not directly python related
On unix, where would you expect a script to appear when you install something?
home/user/bin or maybe in the install location, but export PATH="$PATH:$HOME/install/location/here" is appended to .profile ?
I am new to unix so I don't know what the standard is. I want to automatically add a script to PATH.
hollow venture
Depends on the installation method.
Manual installation, /usr/local/bin/ is a good choice.
If it is packaged, /usr/bin or just /bin is good
vernal crystal
and those will be on path already or should I add those
hollow venture
/usr/bin and /bin should definitely be. /usr/local/bin should also be.
It is by default on arch, at least. (I use Arch, btw).
$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin

Hello , I've been trying to count the number of times a bash script is invoked , but storing count in a file and reading from it , can sometimes cause race conditions , so I dont prefer that method , another thing I came across is the flock which kind of holds a lock on file when an IO is happening on it , but Im not able to implement it properly , can someone give me an insight on this?
#!/bin/bash
file="/tmp/count.cnt"
flock -xn 200
trap 'rm /tmp/count.cnt' 0
RETVAL=$?
echo "acquiring lock"
if [ $RETVAL -eq 1 ]; then
count=$(cat ${file})
if [$count -eq 0]; then
echo "Building now"
docker build -t container . 1>/dev/null
docker run -dit --privileged container 1>/dev/null
nc localhost 1234
else
nc localhost 1234
fi
else
echo "Sleeping"
echo 0 > /tmp/count.cnt
fi
200>/tmp/count.cnt```@tender plinth to lock the file in the current script's context, i've simply used
exec 4<>/my/file/here
flock -n 4
ah thanks @main olive
u dont check if the lock has been acquired successfully or not?

Hi. I am trying to understand what login means in linux.$ w USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT ennozdd :0 :0 10:47 ?xdm? 8:27 0.00s /usr/lib/gdm3/g
ctrl+alt+f3 to see how another console will show up$ w ennozdd :0 ennozdd tty4 - 20:08 13.00s 0.08s 0.05s -bashI also ran multiple instances of gnome terminal to see if each one counts as login but no it didn't make any difference in the output.
on tmux however there are multiple logins```ennozdd pts/2 tmux(11089).%0 20:11 3.00s 0.04s 0.01s tmux
ennozdd pts/3 tmux(11089).%1 20:11 2.00s 0.04s 0.04s -bash

ennozdd pts/6 tmux(11089).%4 20:11 2.00s 0.04s 0.00s w
@humble onyx gnome terminal doesn't use a login shell because you are already logged in when you are opening the terminal
you can start a login shell manually of course
humble onyx
1 - why did tmux make such a difference or why were my terminals not listed?
2 - Does :0 mean there is a GUI login?
3 - $ps aux gdm 1448 0.0 0.0 299432 7156 tty1 ennozdd 10577 0.0 0.5 698416 43256 tty2 Sl+ 20:04 0:00 /usr/share/discord/Discord there is also tty1 and tty2 I see
formal schooner
tmux specifically uses a login shell because tmux windows typically persist after the original login session ended
the idea is that you log in once per tty. tmux is a bit different because your tmux session is meant to be independent of whatever your current session is
https://unix.stackexchange.com/a/336527 :0 is an X11 thing. tty is the linux console. ptty is SSH, gnome terminal, tmux, etc.

In my .bashrc file, how would I access this environment variable?
PAL:DriveLetter=V
The usual $VARIABLE_NAME isn't working. It thinks that everything after the : is a command.
opaque ginkgo
${varname} @tawdry sonnet
tawdry sonnet
That's a step in the right direction, now it just prints a blank line like the variable doesn't exist.
formal schooner
i didnt know you could even have an environment variable with a colon in it
: is special syntax for parameter expansion in bash
so that wont work either
https://stackoverflow.com/a/2821183/2954547 interesting
it might not actually be possible in bash
@tawdry sonnet maybe use python: python -c 'import os; print(os.getenv("PAL:DriveLetter"), end="")'
summer trail
the end="" doesn't really help; if you're using that from a shell script command substitution will strip off a trailing newline so that the end result is the same with or without end=""
I think you're right that there's no way to do it with bash, though. That's interesting.
formal schooner
Good point

how to open arch cli in ubuntu cli?
molten wedge
arch cli is just bash terminal. what you can do in arch cli is the same as what you can do on ubuntu cli
https://hub.docker.com/_/archlinux/ Arch does have a docker image
hollow canyon
i want open arch architecture cli on ubuntu
ember isle
Not quite sure what you mean
The CLI/Terminal that you have on Arch is about the same as you'd have in Ubuntu, the main difference between them would be the package manager/packages if anything
tawny matrix
@hollow canyon you've got a bunch of options here.
First of all terminal emulator (or terminal for short) is the program you open that houses the shell (defaults to Bourne Again SHell or BASH for short).
There are a lot of options for terminal emulators (Termite, Terminator etc) and also for shell (bash, zsh etc). You need to specify which of the two you want to change, -probably the shell- but the default one should be BASH in both ubuntu and arch.
Only way to get a different shell during an arch installation is to use an arch based OS like ArchCraft which uses zsh as the default shell.
Please provide more information so we can help you further
molten wedge
Arch uses zsh during installation too, but it disappears as soon as installation is complete
weirdest shit I've seen
robust cave
it's weird because you don't understand it, the live ISO uses zsh + grml-zsh-config (https://grml.org/zsh/) as the features result in ease of use during installation (completion etc..)
the reason it disappears as soon as installation is complete is because the packages on the live media is separate from the packages you end up on your system
when installing arch, a step is to install the base package (https://wiki.archlinux.org/index.php/Installation_guide#Installation), which among other essential stuff installs bash, which is mandatory and an obvious choice for a default shell
it's up to you to install another shell and use that
molten wedge
yeah ik that.
but during configuring the archiso, what parts of the packages.x64_blahblah dissappear and which one remains?
robust cave
configuring the archiso
I assume you mean during installation,
after a standard installation using the guide (assuming no other packages are installed other than the explicit requirements), the only packages that are installed are linux, linux-firmware and the base package, the contents of which you can see here-> https://www.archlinux.org/packages/core/any/base/
molten wedge
I assume you mean during installation,
No no you assume wrong
i mean the archiso which is used to build the actual iso
@robust cave
robust cave
@molten wedge packages.x64 is all the packages in the live CD (aka Arch ISO) https://gitlab.archlinux.org/archlinux/archiso/-/blob/master/configs/releng/packages.x86_64
I'm not sure what you mean by actual ISO
molten wedge
so if i add Firefox in this list and install this newly built ISO on my computer, will I get Firefox in my new computer or not? @robust cave
robust cave
the Arch ISO is not what ends up on your computer, it's just the tool to help you get everything you need for a functioning arch installation
molten wedge
Is there a way that I build an iso so that Firefox is already there on my pc when I finish installation? @robust cave
robust cave
I'm not sure what you're talking about? you just have to install firefox (like pacman -S firefox in arch) during the installation process, and it'll be there when you finish installation
molten wedge
But suppose I have a large list of packages that I already need installed and I don't want to remember all those names.
for eg if you install Ubuntu on your system, you will find that dolphin file explorer is pre-installed
robust cave
hm, you could always keep the list of packages somewhere, then after a minimal installation install them all at once
if you do that frequently though, maybe look into something like NixOS
I'm not familiar with it though

yeah that could be done

@dull nymph if you can overlook the slightly unfamiliar syntax (but still nothing compared to other, more esoteric languages) then bash is very powerful

basically, I have a remote server running a discord bot, which I can connect to. the way I'm currently updating my code is using some file transfer tools every time I want to update my python code, then ssh-ing in to run the code again. Is there a way to push code from my computer to the server with git, and also force python to restart using the new code, so it doesnt take 5 minutes to update my code?
i know git supposedly can be used to push code there, but I also need the code to restart
the code is running in a screen so it stays even after I close my ssh client

You use GitHub @solar glade?

I do that with GitLab, at least.

wind adder
hey
HELP PLEASE!
I need to get rid off special characters between chr(128) and chr(153)
How do you do that in unix
and also I am getting an Illegal byte sequence error when I am trying use the cut command on file
formal schooner
@wind adder are you asking about doing it on the command line, or in python?
wind adder
Either way
command line would be nice
the problem is the encoding right now
it's trying to read en_UTF-8
and I think this file has characters not supported by that
I am trying to look into perl, but if you are aware of some perl, could you tell me how to do a simple regexp_replace with perl
cat file | perl s/regex/replacement/g
How about that, I have a very specific requirement to block out only certain latin coded characters
formal schooner
as bad as python 2 was with text encodings
python 3 is pretty good
do you know the actual encoding of the file?
wind adder
I think I do let me check
ISO-8859-1
oh actually do u know if tr works with hexcodes
ah dang okay i have to use another encoding
tr -dc '[:print:]' < infile > outfile
same problem, illegal byte seq
formal schooner
python can read that encoding
with open("myfile.txt", encoding="iso-8859-1") as fp:
text = fp.read()
@wind adder
correctly reading the correct encoding is much better than arbitrarily deleting bytes...
wind adder
hmm u know what i think this is probably a better idea
than me trying to pick up sed and awk
at this point in time
still though i dont know if i shud really go the python route
cause the end goal here is to make some kind of a wrapper on an already existing bash command
formal schooner
your program only accepts utf-8 encoding?
wind adder
no no i dont think the encoding is a problem for the other bash scripts
i am trying to build a wrapper on another bash script thats making use of this file , i want to clean up some trouble some characters
formal schooner
why are they "troublesome"? you just need to read the file in the correct encoding
wind adder
we are using that characters properly for oracle db, but for some reason sales force craps out
formal schooner
maybe salesforce requires utf-8 input?
wind adder
the characters cant be processed well on some platforms
ya they might have a restriction
formal schooner
i recommend writing a small python script to convert the file from iso-8859-1 to utf-8
utf-8 is a better and more commonly used encoding nowadays
with open('file.txt', encoding='iso-8859-1') as fp_in:
with open('file-utf8.txt') as fp_out:
fp_out.write(fp_in.read())
that's it
wind adder
okay I will try it, I have to check to see if something in the oracle db is not dependant on those file characters too
thanks.
formal schooner
good luck. tools that use bad old encodings are a real nuisance
wind adder
Yeah agreed

I have a really weird issue with nano + tmux
so basically, when I press the down arrow when my cursor is at the start of line 1(before the a), the cursor moves to before the 2nd line's line number and typing anything messes up that line's display
but this apparently only happens with all of the following: nano with line number enabled, tmux, and windows terminal
nano w/o tmux on wt works normally
nano w/ tmux but using cmd as the terminal works too

Hey guys, I'm trying to use pip on my WSL but I run into this path error. I have added the path to my .bashrc (top row is the cat of .bashrc) but it does not seem to work
Anyone have an idea?
so I added export PATH="/home.." to the .bashrc already
FYI, this is what happens when I try to apt install it
molten wedge
@bitter creek i think you removed the pip from your PATH since pip should be installed in /usr/bin

let me check!

tbh, there's nothing to check. Unless you really need to, you should probably remove the export line from bashrc

I know about ssh using which I can connect to my Machine but how exactly should I run those scripts and host website. Like do we just roll it in terminal? If yes then how can I access that terminal so I can say terminal a script and run again

yeah you have to find the process id for the scraper and kill it @stark tide

@stark tide look into systemd units
you can use them to manage "daemons" aka background processes. Run them at boot, stop/start them, etc
stopping your scraper would be as easy as systemctl stop scraper

hey yall. I was seeing the news about zsh becoming the default shell for mac. When I use the terminal does that mean I have to type zsh every time I use it? On startup it always runs bash too. So do I just disable the bash running on startup or have it run zsh on startup? Thank you!

but im pretty sure that only applies to new computers
fickle wadi
never payed attention to that
well I mean I am running a relatively new system

so just change the shell?

Hello, can somebody help me out with starting a debugging session with pudb? I don't have much experience with Python, so I'm struggling to understand WTF is wrong. My goal is to debug calibre, at this point:
https://github.com/kovidgoyal/calibre/blob/master/src/calibre/ebooks/mobi/debug/main.py#L45
with this debugger:
https://documen.tician.de/pudb/starting.html
I installed it, I insert the breakpoint as the documentation says, I launch the script with
calibre-debug main.py -- /path/to/ebook.mobi
It says ModuleNotFoundError: No module named 'pudb'. Why is it not found if I installed it with pip?
main olive
@desert oasis haven't looked too much into the project, but it may be possible that calibre-debug uses its own virtual environment (where pudb isn't installed)
desert oasis
I see. Where can I see a list of modules that is inside virtual env?
Anyways, I'll go and read virtualenv docs, maybe that will help
main olive
add the following to the top of a file whcih you presume would be run inside the environment when calibre-debug is evoked:
from pip._internal import main as pipmain
pipmain(['freeze'])
this should print all of the installed modules
similarly, you can use pipmain(['install', 'pudb']) to install within the venv
(((this is under the presumption that it does indeed use its own environment)))
how did you install calibre in the first place?
desert oasis
Something weird happens:
from pip._internal import main as pipmain
ModuleNotFoundError: No module named 'pip'
i installed calibre using my distro's package manager and calibre-debug does not use its own environment (and has pip) https://arse.ee/YrPluEy1.png
desert oasis
I installed calibre using their binary installer, and not with my package manager (pacman).
I debug as documented here https://manual.calibre-ebook.com/develop.html#debugging-tips
Basically I set CALIBRE_DEVELOP_FROM to checkout path of calibre and now then it knows where to look for python code.
desert oasis
It works alright, but the question is how to integrate it with external debugger.
main olive
not even a venv, a full separate python instance
honestly, my suggestion? use pacman's version of calibre
desert oasis
So I would have to rebuild it from source with pudb included in order for it to see it?
main olive
just be sure to do sudo /usr/bin/calibre-uninstall first
pacman's calibre uses the system's python install
so pudb etc works
desert oasis
But does pudb work if I install it with pacman? The reason I used their binary installer in the first place was because I could not even use print debugging if I install with pacman.
Although I inserted my print statements in the checked out soure directory and hoped it would respect CALIBRE_DEVELOP_FROM variable. Maybe I should have done it in wherever pacman installed calibre.
main olive
https://arse.ee/bR55YXrX.png works on my machine
although i'm not sure if it respects that env var
desert oasis
I'll try that

Hi Im working on unix terminal with python
im new to unix, how do you make a wrapper, I want to do some re.sub on the files that are passed as arguments to a bash cmd, and then recall the same bash cmd with the new file and same options
anyone have any experience with this
molten wedge
# wrapper.sh
output=$(python my_wrapper filename)
echo "$output"
# my_wrapper.py
import sys
print(sys.argv)
@wind adder Basically you have to catch the print statements in your python script and then use them in your bash commands.
wind adder
Hi IgnisDa thank you for reply, I am using sys.argv but I am having trouble thinking of how to structure this thing in general
molten wedge
In practice you should probably be using argparse
wind adder
right now I have something like this
Test.py:
import sys, re
with open(sys.argv[1],'r',encoding=...) as f:
print(re.sub(r'...','',f.read)
Now I want this to be actually called when lets say they type
Terminal: bash_cmd -iwdg s_list.txt
I will rewrite this bash_cmd
#!/bin/bash
python test.py $1 > $1
bash_cmd "this is the part im confused, how do I make sure all the args are passed in here, and I am not too sure if they will call this command on just one file too"
molten wedge
!code
wind adder
!code-block
shy yokeBOT
molten wedge
#!/bin/bash
output=$(python test.py)
bash_cmd "$output" arg2 --named-arg arg3 --verbose
@wind adder I have no idea what bash_cmd is, so I will leave that to you
wind adder
It's not a real command I am using it as a placeholder for any bash cmd
But okay the thing is, what if they passed in multiple arguments into this bash_cmd to begin with
I want to make sure those arguments and options are still preserved
molten wedge
@wind adder edited previous answer
wind adder
oooo Okay perfect I will try this thanks
molten wedge
Yeah, also make sure to quote your variables like I did so that backslashes are not mangled
wind adder
ah yes

I need help installing python packages!
I'm using a Linux based system that is on a chromebook and I installed everything to run Java files which I think is JDK and Java Envrionement. Now I want to try from python. I need to import a a package using "import turtle" but I'm not sure how to actually do that?
I think I'm suppose to download the linux version on anaconda but I'm not sure if that's the right way or even how to install/run it in my chromebook based linux.
Thanks!
vestal turret
turtle is part of the standard library.
Which distro are you using @sick granite not all of them include it by default
vestal turret
ah, a chromebook
sick granite
Also, is the this appropriate discussion to put this question in?
I figures unix and linux was similar? I'm not sure.
vestal turret
If you've installed that you should be able to import it.
sick granite
and that will give me other general files to import right?
vestal turret
That'll allow you to use pythons tk basked packages, turtle is one of those.
If you've got it you can put
import turtle``` at the top of your filescan I just install all python packages if I exclude "-tk"?
vestal turret
no
sick granite
then how would I be able to install like all the general files for my python class?
Like the way Java uses JDK.
sick granite
hmmmm......so I have the general importable files? just not the tk based ones?
vestal turret
You have the rest of the standard library already
sick granite
how do I check if I have them?
vestal turret
You could try importing a few, but I guarantee you have them.
sick granite
ok
I have another question.
I'm trying to build a computer and I want to make it linux based. Would you recommend a Ubuntu enviornment? Like GNOME or something?
vestal turret
Ubuntu is a fine choice.
sick granite
whats the diff between that and GNOME?
vestal turret
Ubuntu is a distribution (distro), GNOME is a Desktop environment.
They are fundamentally different things
sick granite
so Ubuntu is like my OS and Gnome is just how the desktop will look after processing Ubuntu?
main olive
yeah the top layer of what you see is gnome
the kernel and all services are those of ubuntu

Hmm, you want to parse json with grep?
It might be difficult because json isn't a regular language.

but why you say to use jq
well seems like gron cant find some of the objects in the file :/
@opaque ginkgo gron dont find some objects because of unicode
grep can't parse json
use jq
main olive
can you guys gimme some help with jq
maybe jq can do it and i dont have to code anything like it, but if jq cant do the job that's what i need to do
viscid jungle
Actually, perhaps you could write a small python script to do this?
Python has json parsing in the standard library.
This is the python discord, just saying 😄
And python is available on most unix installations today.
main olive
ye but im parsing stuff thats coming from another software and i dont want to code something just to use more ram
however, my json file contains some unicode as you guys can see on the paste
and even with jq, i dont get the data im interesting in due
parse error: Expected value before ',' at line 1, column 125
and i dont have control of the json data
how it is generated
viscid jungle
Ah right, so it's not necessarily valid json.
main olive
but it seems to generate a valid xml, what similar tools i got for xml?
viscid jungle
Maybe xpath?
main olive
im trying it out, can u help out with the syntax please? first time using it
it should get the object starting from <host..> but only those with the string MyServerV1.1. in the middle
xpath -q -e '//host' goxml.xml
gives me the element i want but i still need to filter the results by MyServerV

I'm working on packaging Ren'Py as a flatpak which succeeds in building and can run some example games, however there are some issues at runtime that I'm trying to tackle. One big issue is that it requires tkinter which seems to be shipped inside the flatpak build, but it can't seem to find that package (looks like tkinter has been moved to /lib/python3.8/site-packages/future/moves/tkinter inside the build) so a lot of GUI functionality isn't accessible.

Last night I tried to dual boot Linux onto my computer, but apparently I had to shrink the main partition to create space for the new one. And it wanted me to defragment before shrinking the main partition. Which I guess makes sense so that you can have contiguous space for the new partition. But it never got above 0% defragmented even though I just reset this computer so why would there be so much to defragment?

@granite aspen were you running the defrag in Windows? Maybe trygparted.... https://gparted.org/livecd.php
granite aspen
isn't that for partitioning if you're currently running linux?
analog jasper
Nah you can run gparted on a live stick
hollow venture
Yup. The link I shared was for the live CD/USB.
The advantage is that you can operate on an unmounted FS, so you know files are not in use.
(Note that I haven't had to deal with a Windows partition since Win 7, so not sure how well it works with win 10).
main olive
I did erase everything and install linux 😛
But yeah the gparted should work, what I used to do before was create a partition in windows using that disk partitioning GUI and then during the live install selected that partition as main one and default windows bootloader partition to install grub.
Now I know I was so dumb doing that.

At First it was like win xp
Then i customised it
But Still It Looks Ugly
eternal swallow
i dont think gentoo linux would be about looks rather than the functionality
quartz zenith
Yeh

bloated
main olive
haha its ok if you want to get into linux
molten wedge
Yeah it is ideal for that. It's extremely stable too.

For me it's less about bloat and more about "I don't trust Canonical"
That said I do use Mint Cinnamon at home on my "big" PC, I'm a big Mint fan

rolling release distro are the best to me

may I ask help for linux bash here?
@half crow you can. The unix channel isn't python-specific.

then, here we go
Hi~~ As the server rules require, I will try to explain my issue the best I can. Please forgive me if my english is not very good and ask me anything. Thank you in advance.
TOPIC: Log commands from different ssh connections to the bash history files
-
Scenario:
Lot of servers Linux Centos 6/7 with 2 users:norootandroot.
It is required to keep a minimum track on the commands issued in SSH bash sessions, without adding more users to
this servers.
Clients are customizable. -
Idea:
Since there is no problem modifying SSH clients, the main idea resides on taking advantage of SSH's SendEnv feature
to send a variable$GIT_NAMEto the server, previously defined and exported when opening a local bash shell~/.bashrc.Given this situation, what would be the best option to keep a track on every "user" identified with the variable
$GIT_NAME?
-Main approach:
My main approach is to make use of the history command in ./bashrc with
PROMPT_COMMAND=history -a $GIT_NAME.history ; echo $(head -n1 ~/.$GIT_NAME.history) >> .bash_history .
Why like this? Well I can't make it work.
Ideally I would type `history` and the format would be something similar to this one:
https://www.linuxtechi.com/enable-timestamp-history-command/
..,but adding the variable if received.
`.bash_history` writes the timestamp with a Unix Timestamp commented before the line, like: ```
#160005455
sudo shred /etc/*
#160005600
ls /etc/ -lhta
#160005941
echo "OK"

I'm trying to print the prime numbers and then count of the prime numbers
But this code of mine will print 100 times of every prime numbers...the count prints 100
molten wedge
if you have an upper range, you can use the Sieve of Eratosthenes method. It's much more reliable, faster and cleaner.
main olive
def prime(n):
if n == 2:
return True
for i in range(2, n - 1):
if n % i == 0:
return False
return True
This is the brute force way to check if a number is prime
Time Complexity; O(n)
def prime(n):
if n == 1:
return False
if n == 2:
return True
i = 2
while i * i <= n:
if n % i == 0:
return False
i += 1
return True
This is the best way to check a number is prime or not
Time Complexity: O(sqrt(n)

what does exporting a variable do?
formal schooner
@warped wing in the shell?
It makes it part of the "environment" which is inherited by child processes
hard bear
@main olive Thanks a lot! I've managed to use your code and fix it a little to make it work
molten wedge
def prime(n):
if n == 1:
return False
if n == 2:
return True
i = 2
while i * i <= n:
if n % i == 0:
return False
i += 1
return True
@main olive i remember this answer was part of project Euler.
