Can you be more specific about what is a point of confusion? Python does not really have global variables. It has module, class, and method scopes. A module-scope variable can work like a global variable for code in the same module. For code in another module, the module name plus dot must prefix the variable. This true for functions as well, except for built-in functions of the language. A function inside a class definition is also called a method. A function may be defined at either the module or class level.

Hi, I'm starting to get confused because you use dot notation to call functions and use variables within modules and classes both. I'll keep going and it will probably clear itself up.

A module can contain many different Python object definitions like: * simple variables * function definitions * class definitions The module also provides a namespace for these definitions for referencing them in other modules. The module is one of the basic structuring elements in the Python language. The class in Python is, like most other object oriented languages, the mechanism for defining the state and behavior of class objects. Python class objects, again like most object oriented languages, encapsulate state (or data) and behavior (functions) into a single software entity.
