Intro to OOP in Python

Learning Outcomes

• What classes are
• The difference between a class and a class instance
• What self means and how it's used
• The __init__() method
• Class and instance variables

Theory

Like we've done before, we're going to watch Corey Schafer's Python OOP 6-part series. In this lesson, you'll be introduced to classes and their basic functionality. Watch the following three videos:

• Classes and Instances Video
• Class Variables Video
• Class Methods and Static Methods Video. Warning: this lesson introduces decorators. It's an advanced topic, which we will discuss in future lessons, so don't be stressed out if you don't understand how to use it.

Knowledge Check

• Explain what classes are and how they are used
• What does self mean and where is it used?
