Introduction

Python is a high-level, interpreted programming language. It is known for its simplicity and readability, making it an excellent choice for beginners. Python is widely used in web development, data analysis, artificial intelligence, and many other fields.

Setting Up Python

Before you start coding, you need to install Python on your computer. You can download the latest version from the official Python website. Follow the installation instructions for your operating system.

Basic Syntax

Python uses indentation to define the scope of blocks of code. Here's an example:

print("Hello, World!")

Variables and Data Types

In Python, variables are names that store values. Values can be of different data types, such as integers, floats, strings, and booleans.

age = 25
name = "Alice"
is_student = True

Control Structures

Python uses control structures to control the flow of execution. These include if statements, for loops, and while loops.

if age > 18:
    print("You are an adult.")
elif age < 18:
    print("You are a minor.")
else:
    print("You are 18 years old.")

Functions

Functions are blocks of code that perform a specific task. They can be defined and called as follows:

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

greet("Alice")

Error Handling

Error handling is an essential part of programming. Python provides a try and except block to handle exceptions.

try:
    result = 10 / 0
except ZeroDivisionError:
    print("Cannot divide by zero.")
