Python OOP Course: Classes, Inheritance, Polymorphism

Create objects in Python by defining a class as a blueprint, using product as an example, and distinguish class attributes from instance attributes while handling object creation and attribute access.

Define instance attributes with a constructor to assign per-object properties like name and price in a Python class, ensuring each instance initializes its own values.

Explore how methods inside a class operate on object data using self, implement a discount method, and call it on objects to update prices.

Explore functional versus object oriented programming by building a product data app, showing input and display with a functional function and a class with constructor, getters, and put data methods.

Explore how inheritance in Python lets a subclass inherit attributes and methods from a base class, illustrated with product and digital product examples.

Learn how multiple inheritance lets a class inherit from several classes, giving a C object access to methods from A and B as well as its own method C.

Explore multi-level inheritance in Python by chaining classes, where C inherits from B and B from A, showing access to A, B, and C methods and contrasting with multiple inheritance.

Explore polymorphism in Python by understanding forms, including operator polymorphism for numbers and strings, and function polymorphism that adapts with strings or lists, with a nod to object oriented programming.

Explore how method overriding achieves polymorphism in Python's object oriented paradigm by overriding a superclass method in a fruit subclass, illustrating when inherited methods are replaced by subclass definitions.

Explore instance methods that operate on an object's instance variables, using self and constructors, implement a hello method to print a name, and compute the length of the name.

Learn how class methods access class variables using the cls parameter and the @classmethod decorator, and why they are invoked on the class rather than an instance.

Explore static methods in Python: they belong to the class, not to instances, require no self, and are called on the class for tasks like adding numbers or circle calculations.

Discover nested classes in Python, where an inner class accesses the outer class and its attributes. See a car example with a steering inner class and static methods.

Learn to design a zoo using nested classes, with a zoo class managing an empty animals list and an inner animal class, supporting add and display operations.

Explore constructor inheritance by showing how a child class inherits the parent’s init method to access and display the balance.

Learn how to override a superclass constructor in a child class, manage balances, and use super to access the parent's balance for a combined total.

Use the super function to access the parent class's attributes in the child, enabling constructor inheritance and combining child balance with parent balance.

Define a vehicle class, create objects with a constructor for name and color, implement an instance method to display attributes, and explore inheritance with a car subclass.

Explore method overriding and constructor overrides in Python OOP with a vehicle and car example, using super, and add class attributes, class methods, and static methods.

Build a student management system in Python using OOP with a student and a school class. Add, display, edit, and delete students stored in a list via user input.

Create a menu-driven Python program to add and display students in a school using a while loop and string choices, with in-memory data (not stored in a file).

Learn to edit a student's data by locating the student via roll number, inputting a new name and age, and updating the records with an edit_student method.

Implement delete functionality in a Python object-oriented programming student management system by adding a delete_student method that removes a student by roll number from the list.
