What is Python?

Python is a high-level, interpreted programming language that is easy to read, write, and learn. It was created by Guido van Rossum and released in 1991.

It emphasizes code readability and uses simple syntax that lets developers express concepts with fewer lines of code.

Why Learn Python?

Python is one of the most loved and in-demand languages in the world. Here’s why:

FeatureBenefit
Easy to LearnClear, readable syntax perfect for beginners
VersatileUsed in web, data science, AI, automation, games, etc.
Huge EcosystemTons of libraries (like Django, Pandas, TensorFlow)
Community SupportMillions of users, tons of tutorials and help online
Cross-PlatformWorks on Windows, Linux, macOS

Where is Python Used?

Python is used in:

  • 🌐 Web development (e.g., Django, Flask)
  • 🤖 Machine learning & AI (e.g., TensorFlow, scikit-learn)
  • 📊 Data analysis (e.g., Pandas, NumPy, Matplotlib)
  • 🤖 Automation/Scripting (e.g., writing bots, task automation)
  • 🕹️ Game development (e.g., Pygame)
  • 📱 App development (Kivy, BeeWare)
  • 🧪 Scientific computing (SciPy, SymPy)

How to Install Python

Step 1: Check if Python is already installed

Open terminal/command prompt:

python --version

If installed, it will show something like:

Python 3.11.4

If not, follow the next steps.

Step 2: Download and Install Python

Step 3: Verify the Installation

After installation, open terminal or command prompt:

python

You should see the interactive Python shell:

>>> print("Hello, Python!")
Hello, Python!

Write Your First Python Program

Let’s create a simple Python program that prints a message.

🖥️ Method 1: Using Terminal or Shell

print("Hello, World!")

Method 2: Using a .py file

1. Open any code editor (e.g., VS Code)

2. Create a new file hello.py

3. Write:

print("Welcome to Python programming!")

4. Run it from terminal:

python hello.py

Output

Welcome to Python programming!

Key Takeaways

  • Python is beginner-friendly and powerful.
  • It can be used in almost any domain.
  • You installed Python and wrote your first script!
  • You’re ready to dive deeper

Task

  1. Install Python and run the print() command.
  2. Create two files:
    • welcome.py → prints your name
    • math.py → prints the result of 5 + 3 * 2
