Introduction to Python

Python is a high-level, interpreted programming language. It is known for its simplicity and readability, making it a great choice for beginners and experienced programmers alike. In this tutorial, we will cover the basics of Python programming.

Python Features

• Easy to Learn: Python has a simple syntax that is easy to understand.
• Versatile: Python can be used for web development, data analysis, AI, and more.
• Open Source: Python is free and open-source, which means you can use it without any cost.

Getting Started

To start programming in Python, you need to install the Python interpreter. You can download it from the official Python website: Python Download.

Basic Syntax

Here is a simple Python program that prints "Hello, World!" to the console:

print("Hello, World!")

Variables and Data Types

In Python, variables are used to store data. The data can be of different types, such as integers, floats, strings, and booleans.

x = 10  # Integer
y = 3.14  # Float
name = "John"  # String
is_valid = True  # Boolean

Control Structures

Python uses control structures like if, for, and while to control the flow of the program.

If Statement

if x > 5:
    print("x is greater than 5")

For Loop

for i in range(5):
    print(i)

While Loop

while x < 10:
    print(x)
    x += 1

Functions

Functions are blocks of code that perform a specific task. You can define your own functions or use built-in functions.

def greet(name):
    print(f"Hello, {name}!")

greet("John")

Modules

Python has a vast library of modules that you can use to extend the functionality of your programs.

import math

print(math.sqrt(16))
