Superclass

As explained in The Well-Grounded Python Developer: How the pros use Python and Flask

A parent class is a class whose attributes and behavior are inherited by another class.

class ParentClass:
    pass
 
class ChildClass(ParentClass):
    pass

How The Well-Grounded Python Developer: How the pros use Python and Flask covers it

How deep it goes

Explains parent-child terminology, inheritance syntax, specialization, and parent initialization through shape examples.

Examples

Uses ParentClass and ChildClass, then develops Shape, Rectangle, Square, and Circle drawing classes.

What it assumes

Assumes familiarity with classes and objects while teaching parent, child, base, derived, superclass, and subclass terminology.

What you can do after

Build inheritance relationships and reuse or specialize parent behavior in Python classes.

How it connects

Connects inheritance with subclasses, derived classes, class design, polymorphic shape behavior, and the DRY principle.
