This video introduces the concept of inheritance in Python, demonstrating how a new class can be created from an existing one. The child class inherits the attributes and methods of the parent class, allowing for code reuse and customization. The video explains how to define a child class and override methods like _init_ and __str__. It explains how inheritance works with classes like Person and Student. It also explores creating custom exceptions and demonstrates how to create and use a Dog class and its subclass Poodle. Finally, it showcases an exercise where users implement a Dog class with a speak method and extend it into a Poodle class with customized behavior.
