what is inheritance in oop python

inheritance is a fundamental concept in object-oriented programming (oop) that allows a class (called the child or subclass) to inherit attributes and methods from another class (called the parent or superclass). this promotes code reusability and establishes a hierarchy between classes.
in python, you can create a subclass by specifying the superclass in parentheses after the class name. here's a basic syntax example:
now, let's delve deeper into this concept with a practical example.
in this example, we have a parent class animal with an __init__ method to initialize the name attribute and a speak method, which raises a notimplementederror to enforce that subclasses must implement this method.
the dog and cat classes are subclasses of animal and inherit its attributes and methods. each subclass provides its own implementation of the speak method, allowing them to exhibit different behavior.
code reusability: you can reuse code from the parent class in the child class, reducing redundancy.
hierarchy: inheritance allows you to create a hierarchy of classes, making the code more organized and easier to understand.
polymorphism: different classes can be used interchangeably, as demonstrated by calling the speak method on instances of both dog and cat classes.
in conclusion, inheritance is a powerful feature in python's oop that facilitates code organization, reuse, and polymorphism. by understanding and effectively using inheritance, you can design more scalable and maintainable software.
