1. Definition of Python

Python is a high-level, interpreted, general-purpose programming language that emphasizes code readability and simplicity. It supports multiple programming paradigms, including procedural, object-oriented, and functional programming, making it suitable for a wide range of applications.

2. History of Python

Python was created by Guido van Rossum in the late 1980s and officially released in 1991.

Reason for Creation

Python was developed to:

The name “Python” was inspired by the British comedy group Monty Python, reflecting the creator’s intention to make programming fun and accessible.

3. Features of Python

Python offers several important features that make it popular:

4. Explanation of Key Terms

4.1 High-Level Language

A high-level language is designed to be easy for humans to read and write, unlike low-level languages that are closer to machine code.

Example:

x = 10
y = 20
print(x + y)

This code is simple and understandable compared to machine-level instructions.

4.2 Interpreted Language

An interpreted language executes code line by line using an interpreter, rather than compiling the entire program at once.

Example:

print("Hello")
print(5 + 3)

Each line is executed immediately, making it easier to detect errors.

4.3 Dynamically Typed

In Python, you do not need to declare the data type of a variable explicitly. The type is determined at runtime.

Example:

x = 10        # Integer
x = "Python"  # Now a string

The same variable can store different types of values.

4.4 Object-Oriented

Object-oriented programming (OOP) is a paradigm based on objects and classes, which helps organize code efficiently.

Example:

class Student:
    def __init__(self, name):
        self.name = name

s1 = Student("Rahul")
print(s1.name)

This example shows how data and functions are grouped into a class.

5. Applications of Python

Python is widely used in various fields:

6. Why Python is in High Demand

Python is highly demanded in the current industry due to:

7. Why Should You Learn Python in 2026

Learning Python in 2026 is beneficial because:

Python remains one of the most relevant and valuable programming skills.

8. Simple Python Example

Program:

print("Welcome to Python")

Output:

Welcome to Python

This simple program demonstrates how easily Python can display output.
