hello

[carmine raptor]

Hey

[prisma storm]

ill give a screenshot

[carmine raptor]

This is the solution I came up with

[carmine raptor]

import sys
import time

print("originalstuff....", end="\r")
time.sleep(1)
sys.stdout.write("\033[K")  # clear from cursor to end of line
print("originalstuff")```

[ripe ibex]

sys.stdout.flush() before sleeping would show you the original stuff too I think

[prisma storm]

yeah. i want just the new stuff

[normal python]

also adding argument flush=True in first print statement

[prisma storm]

so that worked okay

sys.dout.flush() mind telling me about that?

i know what sys means

[young pulsar]

hmm

>>> import sys
>>> help(sys.stdout.flush)
Help on built-in function flush:

flush() method of _io.TextIOWrapper instance
    Flush write buffers, if applicable.

    This is not implemented for read-only and non-blocking streams.
>>>

[prisma storm]

i knwo what flush means

too

[normal python]

print basically writes to sys.stdout

[ripe ibex]

stdout = standard output

[prisma storm]

stdout is still confusing me after the explanation

sorry to waste your time'

[normal python]

imagine stdout as just the output. writing to it is writing to the output. so sys.stdout.write("hello") is telling the OS "HEY stick 'hello' in the OUTPUT please!" so the OS puts 'hello' in stdout which the terminal emulator reads from and displays for you to see

[prisma storm]

so is stdout the output before flush steps in to stop buffering

[normal python]

yep pretty much

[prisma storm]

so stdout is default and you have to tell the computer (unless your os automatically uses flush) to use flush

[normal python]

exactly

[prisma storm]

thank you so much afx

[ripe ibex]

stdout is your output stream
flush (or write) is an operation you perform on stdout

it's not like flush OR stdout are like alternative approaches

[prisma storm]

okay thank you for the specification

okay thank you Raju

[normal python]

imagine like this:

program: hey STDOUT 'a'
stdout: received 'a'
program: hey STDOUT 'b'
stdout: received 'b'
program: hey STDOUT '\n'
stdout: received '\n'
stdout: okay looks like that's it. i'll flush it now!
stdout: my current buffer is 'ab\n' <- combination of stuff gotten from program
stdout: hey TERMINAL here's 'ab\n'
terminal: hey OD here's 'ab\n'

[prisma storm]

so flush is like a mode of stdout

[ripe ibex]

no, flush is an operation on stdout.

[prisma storm]

yes

[ripe ibex]

like an action, not a state.

[prisma storm]

okay thank you

[normal python]

like a toilet. you don't want to waste water every time you put something into it. so you put all your stuff into it and flush once -- works pretty much the same

[prisma storm]

okay. i think i understand it now.

i think my need for help is done for now. i can't explain how appreciative i am of you guys

[normal python]

have fun building your app!

[prisma storm]

more of a terminal program

i am 3 days of old as a python programmer and programmer in general

but thanks
