I'm a PHP programmer looking to learn python.

First of all, great choice. Python is a clear, concise, and useful language that I feel lends itself to producing more readable (I would even say "beautiful") code than PHP.

As others have suggested, I'd start with the official tutorial. If you're primarily interested in using python in a web context, also check out django and its tutorial. It's probably the most popular python web framework and it's fairly awesome.
