hello everyone, how to put the result from os.system into a variable. If you put in , then the console will display the work of this program, and in it will be 0 a = os.system("youtube-dl -параметры")print(a)

Answer 1

os.system only starts the process, it doesn't capture the result.
If you need to get the result of the execution, then as an option you can do it like this:

import subprocess

a = subprocess.check_output('youtube-dl -параметры', shell=True)

Or use Popen
