Python, subprocess: hide console on Windows

utils

import subprocess

IS_WIN32 = 'win32' in str(sys.platform).lower()


def subprocess_call(*args, **kwargs):
    #also works for Popen. It creates a new *hidden* window, so it will work in frozen apps (.exe).
    if IS_WIN32:
        startupinfo = subprocess.STARTUPINFO()
        startupinfo.dwFlags = subprocess.CREATE_NEW_CONSOLE | subprocess.STARTF_USESHOWWINDOW
        startupinfo.wShowWindow = subprocess.SW_HIDE
        kwargs['startupinfo'] = startupinfo
    retcode = subprocess.call(*args, **kwargs)
    return retcode

How to use this function? Argument?
Please explain more.
Thanks

Well, it receives and passes all parameters to subprocess.call, so it works the same way. See https://docs.python.org/3/library/subprocess.html#subprocess.call

Apparently, the only thing that does is to change/add the startupinfo so the window is hidden in Win32.

I wrote this 8 years ago for Python 2 (I think). Maybe Python 3 fixed this.

Thanks for this; really helped me today! Won't need it for Python 3, but not there quite yet.
