We welcome code. Without it we can't begin to help. Also if you get an 
exception please post the traceback also.

I assume you included the form html as a comment, and that the actual 
form is sent to the browser first, then the actual cgi program starts 
with path =

The only problem I see is that the code to write the file is bypassed 
when the path already exists. You should be able to fix that with some 
changes to indentation.

Next time ask sooner. We don't DO homework for students, but are glad to 
help when we see your effort and specific problems.

It is good that you imported the cgitb module. Just add
cgitb.enable()
to activate it.
