Got a source code for python but can't find source module

Google app engine:  but I guess webapp2 can also be installed and run without using the sdk development kit. See 

http://webapp-improved.appspot.com/tutorials/quickstart.nogae.html

Basically use pip to download an unpack all the packages.

So I did it and have all the package installed. 

Still doesn't work as expected, so begin Python tutorial to get an understanding of it.

Follow the tutorial http://docs.python.org/2/tutorial/interpreter.html .

Take an overview of most of it. 

Python fits server:http://docs.python.org/2/howto/webservers.html
