How do you list all child processes in python?

You can’t always log all the sub-processes as they are created, since they can in turn create new processes that you are not aware of. However, it’s pretty simple to use psutil to find them:

import psutil

current_process = psutil.Process()
children = current_process.children(recursive=True)
for child in children:
    print('Child pid is {}'.format(child.pid))
