Introduction

Python is one of the most popular programming languages in the world. Whether you're interested in Web Development, Artificial Intelligence, Data Science, Automation, or Software Development, Python is often the best place to start.

Its simple syntax, powerful libraries, and massive community make it an excellent choice for beginners and professionals alike.

In this guide, you'll learn what Python includes, the core concepts you need to master, and the technologies you can explore after learning the basics.

What is Python?

Python is a high-level, interpreted, object-oriented programming language created by Guido van Rossum in 1991.

It is known for its readability, simplicity, and versatility, making it one of the easiest programming languages to learn.

Example:

print("Hello, World!")

With just one line of code, you've written your first Python program.

What Will You Learn in Python?

1. Variables

Variables are used to store data.

name = "John"

age = 22

2. Data Types

Python supports several built-in data types:

• 
  Integer (int)
  


• 
  Float (float)
  


• 
  String (str)
  


• 
  Boolean (bool)
  


• 
  List
  


• 
  Tuple
  


• 
  Dictionary
  


• 
  Set
  

Example:

name = "Python"

marks = 95

price = 99.99

3. Input and Output

Take input from users and display results.

name = input("Enter your name: ")

print(name)

4. Operators

Python provides different types of operators:

• 
  Arithmetic Operators
  


• 
  Comparison Operators
  


• 
  Logical Operators
  


• 
  Assignment Operators
  


• 
  Identity Operators
  


• 
  Membership Operators
  


• 
  Bitwise Operators
  

Example:

a = 10

b = 5



print(a + b)

print(a > b)

5. Conditional Statements

Make decisions in your program using:

• 
  if
  


• 
  elif
  


• 
  else
  

Example:

age = 18



if age >= 18:

    print("Eligible")

else:

    print("Not Eligible")

6. Loops

Execute repetitive tasks efficiently.

• 
  For Loop
  


• 
  While Loop
  

Example:

for i in range(5):

    print(i)

7. Functions

Functions help organize and reuse code.

def greet():

    print("Welcome!")



greet()

8. Lists

Store multiple values in a single variable.

students = ["Alice", "Bob", "Emma"]

9. Tuples

Tuples are ordered and immutable collections.

data = (10, 20, 30)

10. Dictionaries

Store data in key-value pairs.

student = {

    "name": "John",

    "age": 20

}

11. Sets

Store unique values without duplicates.

numbers = {1, 2, 3, 4}

12. File Handling

Read from and write to files.

file = open("data.txt", "r")

print(file.read())

13. Exception Handling

Handle errors gracefully.

try:

    print(10 / 0)

except:

    print("An error occurred.")

14. Object-Oriented Programming (OOP)

Python fully supports Object-Oriented Programming.

Key concepts include:

• 
  Classes
  


• 
  Objects
  


• 
  Constructors
  


• 
  Inheritance
  


• 
  Polymorphism
  


• 
  Encapsulation
  


• 
  Abstraction
  

Example:

class Student:

    def __init__(self, name):

        self.name = name



student = Student("John")

15. Modules and Packages

Import reusable libraries to extend Python's functionality.

import math



print(math.sqrt(25))
