🏠 Python HOME
Python HOME is the central starting point for all Python documentation, tutorials, and references. It typically includes navigation to beginner, intermediate, and advanced learning paths — like python.org.
📖 Python Overview
Python is a high-level, interpreted programming language known for readability and flexibility. It’s dynamically typed, supports multiple programming paradigms (procedural, OOP, functional), and is widely used in data science, web development, automation, and scripting.
🕰️ Python History
Python was created by Guido van Rossum and first released in 1991. Inspired by ABC language, it aimed to be a language that emphasizes code readability and simplicity. Over time, it evolved into one of the most versatile and powerful programming languages.
🔢 Versions of Python
Python has undergone major revisions:
- Python 2.x: Legacy (deprecated)
- Python 3.x: Current and actively maintained
- Notable versions:
- 3.6 → f-strings
- 3.8 → Walrus operator (
:=) - 3.10 → Match-case statements
- 3.12 → Performance and typing improvements
📌 Always install the latest stable Python 3 version.
✨ Features of Python
- 🔹 Simple and clean syntax
- 🔹 Interpreted and platform-independent
- 🔹 Large standard library and third-party packages
- 🔹 Supports OOP and functional programming
- 🔹 Great for rapid application development
⚖️ Python vs. C++
| Feature | Python | C++ |
|---|---|---|
| Syntax | Clean, beginner-friendly | Complex, verbose |
| Compilation | Interpreted | Compiled |
| Speed | Slower due to interpretation | Faster due to compilation |
| Typing | Dynamic | Static |
| Applications | Web, AI, scripting | Systems, games, performance-critical |
📌 Python is great for rapid prototyping and learning. C++ is best for performance-intensive applications.
🌍 Python Applications
Python is used in:
- 🧠 Machine Learning & Data Science
- 🌐 Web Development (Django, Flask)
- 🤖 Automation & Scripting
- 🎮 Game Development (Pygame)
- 🧪 Scientific Computing (NumPy, SciPy)
- 📊 Data Visualization (Matplotlib, Seaborn)
💻 Python Installation (Windows, Linux, macOS)
✅ Windows:
- Download installer from python.org
- Check “Add Python to PATH”
- Install
✅ Linux (Debian/Ubuntu):
sudo apt update
sudo apt install python3
✅ macOS:
Use Homebrew:
brew install python3
📌 Verify installation using python --version.
⚙️ Python Environment Setup
Once installed, choose an IDE or text editor:
- ✅ VS Code – Lightweight and extensible
- ✅ PyCharm – Full-featured IDE for professionals
- ✅ Jupyter Notebook – Ideal for data science
Set up the PATH variable and use the terminal or integrated shell to run Python scripts.
🧪 Python Virtual Environment
A virtual environment allows you to manage dependencies separately for each project.
python -m venv myenv
source myenv/bin/activate # Linux/macOS
myenv\Scripts\activate # Windows
📌 Helps avoid version conflicts between projects.
🧠 Python Interpreter – Interactive & Script Modes
- Interactive Mode: Run Python commands one at a time using:
python - Script Mode: Save Python code in
.pyfiles and run with:python hello.py
📌 Both modes are useful — one for quick testing, the other for building programs.
👋 Python Hello World Program
Your first Python script:
print("Hello, World!")
📌 Save this as hello.py and run using python hello.py. It prints a simple message to the screen.
📚 Python Syllabus
A typical beginner-to-advanced Python syllabus includes:
- Syntax, Variables, Data Types
- Conditional Statements, Loops
- Functions, Modules
- Lists, Tuples, Sets, Dictionaries
