How do classes work? (rectangle)

[ichabod801]

In addition to what buran recommends, I would say document, document, document. Add a docstring to the class and each method:

class Dummy(object):
   """This is the docstring for the class."""
   
   def foo(self, bar):
      """This is the docstring for the foo method."""

In the docstring you put a description of the class or what the method does. You can also put in a list of methods and attributes for the class, or a list of parameters for a method. Docstrings help explain your code to other programmers (including yourself in six months) and are available with help(Class) or help(Class.method) in the interactive console.
