Python3 - running two functions at once

[hirushaadi]

Language: Python 3

 

What i tried:

from multiprocessing import Process

from threading import Thread

 

what i want to do:

i want to run these two functions at the same time

SHOW_THE_GUI()
ANOTHER_FUNCTION() # at the same time 

and the ANOTHER_FUNCTION() has a time.sleep(10). so, whenever its been excecated, it says that Python3 is not responding for the last 4 seconds and come back to the normal state. i dont want that to happen. i want both of the functions to run parallelly

it's not enough to just import the libraries, you need to spawn new threads or processes.

sorry i didnt mention what i did completely!

 

def IDEK_BRUH():

    processes = []
    # num_processes = os.cpu_count()

    p = Process(target=shit)
    processes.append(p)

    p2 = Process(target=swgui.TO_DO_LIST_GUI())
    processes.append(p2)
    

    for p in processes:
        p.start()

    for p in processes:
        p.join() 

if __name__ == '__main__':
    IDEK_BRUH()

 but, still, this runs one after one

How do you know that?

because, 1 function creates some folders and files, delete some files while the other function shows a GUI to distract the user. 

 

if i put p1 as gui and p2 as other_function, the other_function wont run until i close the gui ( tkinter window ) and if i change the order, the GUI wont show up until the other_functions finishes executing.

I don't see any problems with the starting method, if it doesn't work there must be something blocking your process inside the function you're calling.

shall i message you the code? because i think, sharing it here will violate some Rules of this forum

it's best to post it here using code tags, you can use spoilers if it's too long

The problem may be with you calling join. That makes it join the master thread and blocks until whatever called join finishes.

its something that harms the computer and i think, sharing that kind of things will get this thread closed and even may block my account ( im not sure about that  )

Cpython does not support multithreading as far as I know.

That's partially right. You can spawn different threads by the same Python process but they will not run in parallel (they will alternate; while one is sleeping, another one will be running). But multiprocessing (spawning two separate Python processes by the same script) is a workaround.
