## 🚀 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:
```python
"""
================================================================================
File: filename.py
Topic: Topic Name
================================================================================

Description of what the file covers...

Key Concepts:
- Concept 1
