Introduction to Python Programming

Brief History of Python

Python was created by Guido van Rossum in the late 1980s and officially released in 1991. It was designed to emphasize code readability and simplicity. Over the years, Python has grown to become one of the most popular programming languages in the world.

Applications of Python

Python is used in a wide range of applications such as:

Web Development (using frameworks like Django and Flask)
Data Science and Machine Learning
Automation and Scripting
Artificial Intelligence
Game Development
Internet of Things (IoT)

Installing Python and Setting up the Environment

To start coding in Python, you first need to install it from the official website python.org. After installation, you can use built-in IDLE or install code editors like VS Code or PyCharm for a better development experience.

How to Run a Python Script

Save your Python code in a file with a .py extension. Then, open your terminal or command prompt, navigate to the file's location, and run:

python filename.py

Introduction to Python REPL (Interactive Shell)

Python REPL (Read-Eval-Print Loop) allows you to type Python commands and see the results immediately. You can start the interactive shell by simply typing python in your terminal. It's great for quick testing and learning.

Simple Python Example

Here is a simple Python program that prints a message:

print("Hello, World!")

Output: Hello, World!
