Python Decomposition Examples for Beginners

📚 Quick Study Guide

• 🧱 Decomposition: Breaking down a complex problem into smaller, manageable sub-problems.
• 💡 Benefits: Improves code readability, reusability, and maintainability.
• 🔨 Functions: Key tool for implementing decomposition in Python. Each function solves a specific sub-problem.
• 📦 Modules: Grouping related functions and classes together for better organization.
• 🌱 Example: Decomposing a task like 'making a sandwich' into 'gather ingredients', 'prepare fillings', and 'assemble sandwich'.
