Python - Introduction

What Is Python?

Python is a popular, high-level programming language known for its simple syntax and readability. It was created by Guido van Rossum and first released in 1991.

Python is easy to learn, making it a great choice for beginners who want to start their programming journey.

Python is used in web development, data science, artificial intelligence, machine learning, automation, and many other fields.

Why Should We Learn Python?

There are several reasons to learn Python:

• Easy to Learn: Python has simple and readable syntax.
• Beginner-Friendly: You can write programs with fewer lines of code.
• Versatile: Python can be used for many different types of applications.
• Large Community: Many developers share tutorials, libraries, and solutions.
• Open Source: Python is free to use.

First Python Program

Let's write our first Python program!

print("Hello, World!")

Output:

Hello, World!

The print() function displays text or other values on the screen.

Basic Features of Python

Python provides several useful features:

1. Simple Syntax

Python code is easy to read and understand.

name = "Gowtham"
print(name)

Output:

Gowtham

2. Variables

Variables are used to store data.

`name = "Python"
age = 35

print(name)
print(age)`

3. Data Types

Python supports different types of data, including:

• int — Integer numbers, such as 10
• float — Decimal numbers, such as 10.5
• str — Text, such as "Hello"
• bool — Boolean values, such as True and False
• list — A collection of items, such as [1, 2, 3]
• dict — Data stored as key-value pairs, such as {"name": "Gowtham"}

4. Cross-Platform

Python works on different operating systems, including Windows, Linux, and macOS.
