Introduction to Python

Learn what Python is, why it is so popular, and how to set up your development environment.

What is Python?

Python is a high-level, interpreted programming language created by Guido van Rossum and first released in 1991. It emphasizes code readability and simplicity, making it one of the best languages for beginners and one of the most powerful for experts.

💡

Python is currently the #1 most popular programming language in the world according to the TIOBE Index and Stack Overflow Developer Survey.

Why Learn Python?

  • â€ĸMost popular language for AI and machine learning
  • â€ĸExcellent for data science and analytics
  • â€ĸGreat for web development (Django, FastAPI, Flask)
  • â€ĸPowerful for automation and scripting
  • â€ĸHuge ecosystem of libraries and frameworks
  • â€ĸBeginner-friendly syntax that reads like English

Your First Python Program

Let's write the classic "Hello, World!" program. In Python, this is just one line:

python
# Your first Python program
print("Hello, World!")

# Output:
# Hello, World!
ℹī¸

The print() function outputs text to the console. Lines starting with # are comments — they are ignored by Python and are used to explain code.

Installing Python

Download Python from python.org. Choose Python 3.11 or later. During installation on Windows, check "Add Python to PATH".

bash
# Verify installation in your terminal
python --version
# or
python3 --version

# Expected output:
# Python 3.11.x
