Treffer: Exploring Python.

In the previous Charpter we entered our Python code a line at a time, but now we are going to put the interactive interpreter to the side and start creating Python files. In this Charpter we will cover more of the building blocks of Python code, and show you how to use classes to help with creating games. We will also explain how to use the code libraries that come with all installations of Python. [ABSTRACT FROM AUTHOR]
