Class Inheritance in Python

An explanation of class inheritance in Python which enables a class to use the data fields and methods defined in other classes. This video was made for students of the Rice University Coursera course "An Introduction to Interactive Programming in Python". The example code is available here: http://www.codeskulptor.org/#user24_y97sRHrRAyGWCBe.py ***There were 2 minor errors I noticed after uploading*** 1. When describing the __init__ method I said that Python passes a "copy" of the object to the self input rather than a "reference" to the object. 2. I accidentally used the term "function" instead of "method" when talking about the overriding drive() method near the end... old habit!
