I have written a Python script with a wxPython GUI that uses subprocess.Popen 
to open a list of files that the user provides. One of my users would like to 
be able to run a Python script with my application. The Python script he is 
trying to run uses the command line and gets keyboard input from the user 
several times.

The problem is that if the Python script is run on Windows with 
subprocess.Popen, no command prompt is shown (my GUI application is a .pyw 
file). The user's script runs silently but then does not quit because it is 
waiting for input, but there is no way for the input to be given, since there 
is no command prompt visible.

I think this may be related to the fact that I am calling subprocess.Popen with 
shell=True. I tried calling it with shell=False (the default), but then I got 
an error that the file is not a valid Win32 application.

I would appreciate any help with this problem.
