it's likely that your vscode is configured with a different python than the one in your terminal
pip -V
can't really follow what's going on in your gif ... if you somehow can't select the same python version as your pip uses, I don't really know how to help (don't use vscode myself)
final jewel
(you may have already learned that...) to activate pygame, you do something that is meant to expose the name pygame to your program
the two things for that:
(1) you need to install pygame
(2) once installed, you would import pygame
once you import it, the name pygame is available to yourr program, and you can use it. sometimes, a name (such as pygame) will have pieces attached, that you can get by their name, for example, if x and y were pieces of pygame, you could access them using pygame.x and pygame.y (so, note the "." operator, for that)
you can start to learn to use pygame, there are lots of tutorials, some videos
pygame itself, is a "python module" that can be installed using pip
@sullen iglooare you here?
sullen igloo
Yes
Python -v does not produce any output
I think the tutorials would be a great place to start. I agree
final jewel
howbout: python (no args)? (to get out, ctrl-D)
let's see if you can import pygame...
sullen igloo
Apparently putting Pygame in the name of the program is a big no no
frank marlin
pip -V ? it should show the path to pip... which should match the path to your python installation (to some degree)
final jewel
you can also say: which pip (especially if you're running linux)
sullen igloo
$ pip -V
pip 23.0.1 from C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.10_3.10.3056.0_x64__qbz5n2kfra8p0\lib\site-packages\pip (python 3.10)
final jewel
oh, windows?
sullen igloo
my bad I typed version
frank marlin
that looks like a microsoft store version.
did you also install python from python.org?
final jewel
yeah, and backslashes for dir separrrrrrators
frank marlin
then those two versions are probably conflicting
sullen igloo
how do i remove versions?
frank marlin
go to your windows settings -> apps -> search for python, and try to uninstall the microsoft store version (3.10 it seems)
final jewel
hmm. keyboard acting up
sullen igloo

on it
found it... uninstalling
frank marlin
note: after that "pip" might no longer point to the same python version, so a reinstall of pygame might be needed (and restart of vscode before that to reset your terminals - so they find the new pip location)
final jewel
python is pretty completely object oriented... meaning all values, even integers, and bools (like True and False) are ob jects
frank marlin
python is pretty completely object oriented... meaning all values, even integ...
that's kind of unrelated to the topic though
final jewel
to create your own kinds of objects, you can make your own "class", and then use that class to make objects
buttt more on that later

$ python hello_world_game.py
Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases.
which is he gonna install? or did he already?
frank marlin
yea, it's possible you didn't install python into PATH on installation
try to use py instead
(and py -m pip install pygame )
sullen igloo
yea, it's possible you didn't install python into PATH on installation

its downloading pygame!

output-> I percieve python 3.10 is gone. so I need to switch to the newest version
frank marlin
in vscode? you probably need to switch to the correct python version yes.
py -c 'import sys; print(sys.executable)'
see if "which python" says aomething (leave the quotes out though)
frank marlin
^ (only works if python is on PATH, which doesn't seem the case)
sullen igloo
@frank marlin on it
@final jewel that makes sense
Andrew@DESKTOP-CGDG53G MINGW64 ~/Desktop/pygame_projects
$ py -c 'import sys;
> print(sys.executable)'
C:\Python312\python.exe
that should print the path to the python.exe, that py uses by default.
try to find/select it in vscode.. I think in doubt you can even open a file browser and select it directly.
sullen igloo
@final jewel
which python output
Andrew@DESKTOP-CGDG53G MINGW64 ~/Desktop/pygame_projects
$ which python
/c/Users/Andrew/AppData/Local/Microsoft/WindowsApps/python
that python is something else I believe.
it's a "placeholder" app, that's not actually python
final jewel
heyy it works 🙂 so: which someexe tells you where on the disk someexe is
you can also try: which py
frank marlin
you can also try: which py
py is in system32 ... which will not point to the actual python that py uses, as the py command only delegates to the actual python exe ... 😉
final jewel
yep, that's hello world on a pygame window?
sullen igloo
@frank marlin @final jewel
Thank you! both of you! how can I get better at troubleshooting
frank marlin
which is why I showed how to print the actual python.exe with py, using sys.executable.
sullen igloo
@final jewel
correct sir
final jewel
so you used pygame (so you would have had to "activate" it by making the name "pygame" visible to your code, by importing it
frank marlin
<@404648068164878347> <@975631171721502751>
Thank you! both of you! how can I...
really only with experience. I already knew that microsoft store version can cause pip issues (due to people having issues with it here repeatedly), and I know that a lot of people forget to add python to PATH when installing (it's a checkbox on the installer)....
using py is often a fail safe option on windows to some degree.
sullen igloo
does this come by working on projects and than getting to a point where you observe open tickets on here and see other troubleshooters work? Maybe making notes about solutions? I am considering that being the path forward.
final jewel
I'll have to agree: you need to see what python does, and when python does -not- do that, you would try to figure out why
that part of troubleshooting is called "determining the problem"
frank marlin
does this come by working on projects and than getting to a point where you obse...
looking at other peoples issues definitely helps. But the whole python ecosystem is quite complicated - especially if multiple versions are involved ... but I always thought using different python versions on windows was way easier than on linux 😄
final jewel
certainly, you can learn by observing others, sure; ultimately, you'll be able to learn by obseeerving what python does when it runs -your- code
(sometimes others will be working on things that you're not famiiar with yet)
sullen igloo
i will try to build more python projects and develop my trouble shooting skills further. but I need to define the problem further
sullen igloo
yeah
final jewel
ok, start a python... let me know when it prints its >>> prompt
then we can get started
final jewel
well probably in the windows prompt
you can start it using that bash shell if you want
just let me know when you get the >>> prompt
sullen igloo
I am ready
final jewel
ok, first: variaables... remember I said all values in python are objects?
sullen igloo
yes
I have taken codecademys courses on object oriented programming, functions, and variables.
final jewel
objects can have all kinds of different types... two basic types are: integers and strings
sullen igloo
I have a basic understanding of data types as well, lists, strings, dictionaries, and tuples
but I am
struggling in troubleshooting
final jewel
a variable can hold an object
ok good... I'll hurry up through this part then
run this at the python prompt (the >>>): a = "hello"
final jewel
good
now you have a name, "a", that is bound to the object, which is a strong
sstring
one thing you can use for trouble shooting, is the print cmd
you can print a literal value:
sullen igloo
ok
sullen igloo
a = "hello"
>>> print("hi there")
hi there
>>>
Hey @sullen igloo!
final jewel
yes, 'hello world' is also a "literal value" (which, like all other data in python, an object)
sullen igloo
print("hi there")
technology hates me
final jewel
try shis: print(a)
sullen igloo
print(a)
hello
final jewel
technology is like data, it hhas not ability to feel anything (like hate)
since the thing in the variable a is an OBJECT, it has a type
try this: type(a)
sullen igloo
type(a)
<class 'str'>
final jewel
so you know about indents
final jewel
C would do something like
if(somecondition)
{
dosomeeething
}
whereas python,
if condition: (note! colon important)
do something
but you know that stuff already... just a reminder
back to variables...
do this: b = "world"
sullen igloo
ok
final jewel
then try: a + 5
sullen igloo
b = "world"
final jewel
see what THAT gets ya
sullen igloo
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: can only concatenate str (not "int") to str
final jewel
can't add string and int
try: a + str(54)
that str() converts whatever it gets to a string
sullen igloo
a + str(54)
'hello54'
final jewel
now try: a + b
sullen igloo
a + b
'helloworld'
final jewel
yep, when there was NOT a space before
and finally, you can try these:
a = 5
b = 4
and then,
a + b
sullen igloo
a + b
9
sullen igloo
a + str(b)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for +: 'int' and 'str'
final jewel
can't add an int and a string
notice you're getting a "TypeError"
that will be important later
sullen igloo
so that means I cannot add str to integer
final jewel
yes
but you CAN add string to string and int to int
one thing... the + SEES the types on the left and the right of the +
so it's SENSITVE to the type
sullen igloo
oh! so if it shows type(int) type(str) is unacceptable
sullen igloo
I did not know that
sullen igloo
attempting
"hello" * 5
'hellohellohellohellohello'
lol
thats interesting! it multiplied the string values by 5
final jewel
yeah, that can be handy sometimes
sullen igloo
🙂 I need to write that down
final jewel
so... this has been a little thing about how python is object oriiiented
-everything- is an object, all objects have a type
objects are "first-class", which means:
- you can assign any object to a variable
- you can accept an object as a parameter to a function
- you can have a function "return" an object, so it becomes the "value" of the function
sullen igloo
return allows values to escape the function call. they don't hold data but they are the calculated outcome
final jewel
there are a couple more "rights" a first-class object has, I forgot em
yeah, return can throw out any kind of value
so that's it.. those things can help with some kinds of troubleshooting
sullen igloo
I really appreciate it jimm
final jewel
welcome 🙂
sullen igloo
it sounds to me like the next thing I need to do is build more small projects
and than eventually, a mid project
and maybe, with the help of a team, helpful software
final jewel
yeah, and/or do more tutorials (which are usually projects that it gives you a piece at a time, and explains the piece)
sullen igloo
Any resources you reccomend in particular?
final jewel
part of troubleshooting is making sure you have the program typed in right
it seems like you have basic python, syntax, conditional structures
there's a book that might be handy
sullen igloo
I will have this bookmarked. 🙂
final jewel
I dunno if you want this, but I'll offer: I got an 11-hour video that does a pretty good job of teaching basic python
sullen igloo
could you send me the link?
final jewel
this is something else: https://www.practicepython.org/
sullen igloo
sees practice python.org
reviews material
I can finally work to do list comprehensions which are annoying to me, but necessary.
final jewel
sullen igloo
subscribed!
sullen igloo
I did not provide the context that was my fault
Thank you for these resources, can I send you questions from time to time?
or just use the python discord?
final jewel
sure... and, you can also ask the people on the discord, some of whom are python devs
sullen igloo
🙂 thank you for your help!
final jewel
welcome 🙂 good luck... oh by the way, are you using git?
final jewel
good
final jewel
very good... looks like you have pretty much everything you need
sullen igloo
Well...
one more thing
so in python apparently you write and or type out things that you than create later.
my second main problem has been trying to figure out what tools to use next
i've done tutorials and they are great but I am seeing a lot of len(range) stuff
python combos
how do I learn those?
sullen igloo
I want to use these resources when I troubleshoot next.
sullen igloo
he seems to be a fast talker and very blunt 🙂
sullen igloo
I promise to review these materials 🙂
thank you jimm I will be reaching out in a week or so 🙂 its cool to meet a new friend.
