Ever wondered why Python Tuples are faster and use less memory than Lists?

In this video, we go beyond syntax and visualize how Python actually stores Lists and Tuples in memory.

You'll learn:

• How Python stores objects using references (pointers)
• Why Lists allocate extra memory slots
• What happens during append() operations
• List over-allocation and reallocation
• Why Tuples are immutable
• Why Tuples are faster and more memory efficient
• Common misconceptions about Python memory storage
• Internal memory diagrams and visual explanations

Topics Covered:
✓ Python Memory Model
✓ List Internals
✓ Tuple Internals
✓ References vs Values
✓ Over-allocation Strategy
✓ Reallocation
✓ Cache Locality
✓ Performance Optimization
✓ Python Internals

If you're learning Python, preparing for interviews, or want to understand how Python works under the hood, this video is for you.
