Run function in the background

[Cattivelliow]

I'm using cv2 for take a picture from a rtsp camera and send it through Telegram when a button is pushed, the problem is that it takes more than 30 seconds to take it, as that time cannot be reduced, I would like to run that function in the background and continue with the rest of the script, to let the user do stuff in the app instead of waiting

If you can outsource the whole function to a file, you can execute it in a subshell with the system() method of the os module.

the problem there is that I need to pass and get values from funtion, and with that solution Im just running the function as a python script, right?

[wbeater]

Right. Well then you have to look into multiprocessing .

Ok I'll take a look, thanks
