[Tutor] Automated Breadcrumb -- help for a PHP user

[Chris Heisel]

I aplogize, I didn't mean to indicate that I wanted to write PHP in 
python, I'm trying to migrate to python because I enjoy the elegance of 
the language, I should have clarified my question a bit.

I'm used to the PHP environment where I can access a page's URL and 
other attributes by accessing the various global system arrays.

I have not done any traditional CGI programming, so I'm not sure about 
how to pass information, such as an HTML page's URI, to my python script.

I'd love to use some of the frameworks you mentioned but I'm in a 
corporate environment designing a system for other Web producers who 
will be editing pages via BBEdit and then uploading to the server, so 
I'm trying to keep the set up as simple as possible.

Danny's answer was helpful because its sent me down the cgi path and I'm 
doing some RTFM about cgi and the various variables available...

So apologies all around, I should have clarieid that I wasn't used to 
the python way of accessing global page variables when being used as a 
CGI script, and not that I was confused about the language constructs to 
  output the trail...
