🚀 How to Use

1. Start from basics: Begin with 01_basics and work your way up
2. Run the files: Each file is executable: python 01_print.py
3. Read the comments: Each section is thoroughly explained
4. Experiment: Modify the code and observe the results

🛠️ Prerequisites

• Python 3.10+ recommended (for match/case support)
• Python 3.8+ minimum (for most features)

📝 File Structure

Each file follows this structure:
