Track 11 · Lesson 7 of 12

Inheritance

Build specialised classes on top of general ones, inherit their attributes and methods, and test types with isinstance and issubclass.

You will be able to

• Recognise an is-a relationship and model it with a subclass
• Define a subclass that inherits __init__, attributes and methods from its parent
• Add new methods and class attributes in a subclass
• Explain how Python looks up a method through the class hierarchy
• Use isinstance and issubclass, including with subclasses
