Question

I have one Python module that can be called by a CGI script (passing it information from a form) or from the command line (passing it options and arguments from the command line).
Is there a way to establish if the module has been called from the CGI script or from the command line ??

Answer 1

This will do it:

import os
if os.environ.has_key('REQUEST_METHOD'):
    # You're being run as a CGI script.
else:
    # You're being run from the command line.
