Just a general bit of advice: You will learn more iterating through "change the code, save the file, execute the code, repeat" than any amount of plain reading. When I learned Python, I sat down with Dive Into Python and the command line.
Completely Agree though on this: "change the code, save the file, execute the code, repeat"
Here's a first step for you - you've got a website somewhere - getting it running on your local machine. It might be worth installing something like VMWare Player and setting up a linux "virtual machine" - you can download pre-configured ones. (To translate - that basically means your windows computer can pretend to be a linux server - and that pretend server can run all of your programs - without changing anything on your own system)
Regardless of how you do it - let me repeat. Set it up locally and play with it. Change. Save. Test. Repeat.
