How Python Handles Imports Internally 🧠 45 || Python ka Pitara || DeathCode
🧠 `import` likhna easy hai… par Python uske peeche kya karta hai, pata hai?
Is video me hum Python ke import system ka deep internal breakdown dekhenge —
kaise modules locate hote hain, kaise load hote hain, aur kaise caching se performance fast hoti hai! ⚡

Agar aapko kabhi confusion hua ho:
module dobara execute kyun nahi hota?
`sys.modules` kya karta hai?
circular imports kyun toot-te hain?

Toh ye video aapke liye GOLD hai 🥇

🎯 What You Will Learn:
✅ Python ka `import` statement internally kaise kaam karta hai
✅ Import execution lifecycle (search → load → cache)
✅ `sys.path` aur module search order
✅ `sys.modules` cache ka role
✅ `importlib` se dynamic imports
✅ Reloading modules & cache invalidation
✅ Circular imports kaise hote hain & kaise solve karein
✅ Performance impact of imports

📌 Concepts Covered:
✔ Python Import Machinery
✔ Module vs Package
✔ `sys.path`, `sys.modules`
✔ `importlib.import_module()`
✔ Module Caching Strategy
✔ Circular Import Problem
✔ Reloading & Lazy Imports
✔ Best Practices for Clean Imports

🧪 Real-World Examples You’ll See:
Import execution tracing (print-based + debug)
Why a module runs only once
Breaking circular imports cleanly
Dynamic plugin-style imports using `importlib`
Reloading a module safely
Measuring import-time performance
