Classes and Methods Cheat Sheet

In the past few videos, we’ve seen how to define classes and methods in Python. Here, you’ll find a run-down of everything we’ve covered, so you can refer to it whenever you need a refresher.

Defining classes and methods

 

 

Classes and Instances

• Classes define the behavior of all instances of a specific class.
• Each variable of a specific class is an instance or object.
• Objects can have attributes, which store information about the object.
• You can make objects do work by calling their methods.
• The first parameter of the methods (self) represents the current instance.
• Methods are just like functions, but they can only be used through a class.

Special methods

• Special methods start and end with __.
• Special methods have specific names, like __init__ for the constructor or __str__ for the conversion to string.

Documenting classes, methods and functions

• You can add documentation to classes, methods, and functions by using docstrings right after the definition. Like this:
