Polymorphism In Python
Polymorphism is a fundamental concept in OOP. polymorphism can be achieved through method overriding and method overloading.
Inheritance In Python
In Python, Inheritance is a mechanism that allows a class to inherit properties and methods of another class. This promotes code reusability.
Python Classes and Objects
Object is the most basic concept and a key to understand the Object-Oriented programming .Object has two characteristics, State and Behavior.
Python Functions
Functions are reusable blocks of code that allow you to break down your program into smaller, modular components. They are defined using def keyword.
Python FOR loop
Python loop is used to iterate over a sequence of elements. Sequence can be a list, tuple, string, dictionary, or any other iterable object.
Python While Loop
Loops are essential constructs in Python for iterating over collections of data or executing a block of code repeatedly.

python list examples
Python List
A Python list is a data structure that is used to store a collection of items. Lists are ordered, mutable (modifiable), and can contain elements of different data types, including integers, floats, strings, or even other lists.
Python Data Types
Data Types in Python
Python provides Numeric data type like int, float, complex. Sequence type like List and Tuple, Mapping type Set type , Boolean type and Binary type.
python variables
Python Variables
variables are used to store data values. They are like containers that hold information which can be referenced and manipulated throughout the program.
