You don't need mod_python/cgihandler to run CGI scripts. Rather than
bring mod_python into the picture and confuse things, set up Apache to
run your script as a traditional CGI script instead.

BTW, the fact that mod_python is loaded means that CGI scripts aren't
the only way of using Python available to you as you seem to think.
So, suggest you do some research as to what the differences are
between CGI and mod_python.
