It will be a new subprocess option to not create a new window. Note that this option would also hide the window of GUI programs that do not (intentionally) ignore SW_HIDE, such as notepad.Ĭan I work on this? I'm not sure of it's status, though. Other platforms could simply ignore it, in contrast to writing platform-dependent code that passes startupinfo. Hiding the console is required often enough that a keyword-only parameter for this would be useful. It would be convenient to add an argument to suppress the command prompt from popping up when using subprocess.Popen with shell=False on Windows, many users are missing the feature and these are many similar feature request questions like the following Third, I found QProcess within Qt won't pop up the command prompt in using. Second, the popping up command prompt would interrupt users and do bad to user experience of GUI applications.
