🧹 [code health improvement] Replace wildcard import with specific import

[ManupaKDU]

🎯 What: Replaced the wildcard import from math import * with a specific import from math import factorial in Learn Giraffe.py.
💡 Why: Using wildcard imports makes it unclear which functions are being brought into the namespace and can lead to naming collisions. Since only factorial is used from the math module in this script, importing it explicitly improves readability and maintainability.
✅ Verification: Ran python3 "Part-1/wHATTA/Basics/Learn Giraffe.py" locally to confirm the original functionality and output are fully preserved without errors.
✨ Result: A cleaner namespace with clear, explicit dependencies.
