The force_hide option could also force the use of a new hidden window, even if the current process has a console. That way the output is always hidden. For example:
if force_hide or shell:
if force_hide and not (creationflags & _winapi.DETACHED_PROCESS):
creationflags |= _winapi.CREATE_NEW_CONSOLE
startupinfo.dwFlags |= _winapi.STARTF_USESHOWWINDOW
startupinfo.wShowWindow = _winapi.SW_HIDE
One can also use CREATE_NO_WINDOW to create a console that has no window, as opposed to a hidden window. For example:
if force_no_window:
if creationflags & _winapi.CREATE_NEW_CONSOLE:
raise ValueError('force_no_window cannot be used with '
'CREATE_NEW_CONSOLE')
creationflags |= _winapi.CREATE_NO_WINDOW
