Prevent python windows from being focused

问题:

I am running a Python script on windows 7 that opens a subprocess every few seconds. This subprocess opens a window and grabs focus, disrupting any attempt by the user to do normal work while the script is running. I do not have the ability to modify the subprocess code itself. Is there a way to designate all subprocesses opened by a python script as not-focused?

CLARIFICATION: I need the window to open and be viewable/selectable, just not immediately jump on top of everything else that is going on. In other words, it need to open in the background, not force itself into the foreground.

Here is how I did this last

# Hide the cmd prompt window
startupinfo = subprocess.STARTUPINFO()
startupinfo.dwFlags |= subprocess.STARTF_USESHOWWINDOW
startupinfo.wShowWindow = subprocess.SW_HIDE
p = subprocess.Popen(args, startupinfo=startupinfo)

You can run processes with a variety of flags with subprocess.call

This sample executes the console app with no UI whatsoever:

>>> import shlex, subprocess
>>> subprocess.call("C:\Windows\some_console_app.exe", shell=True)
