In this video, we’ll explore how Python stores and manages variables in memory.
A solid understanding of variable storage helps you write smarter, optimized, and more efficient code. You’ll also learn why, in Python, everything is treated as an object and how variables actually reference these objects in memory.

What You'll Learn:

•⁠ ⁠Variables as References – Understanding that variables don’t store values directly but point to objects in memory
•⁠ ⁠The ⁠ id() ⁠ Function – Checking the unique memory address of objects and how Python sometimes reuses them
•⁠ ⁠Memory Optimization – How Python saves space by reusing small integers and immutable objects
•⁠ ⁠String Interning – Why frequently used strings like ⁠ "Navin" ⁠ are reused for efficiency
•⁠ ⁠Garbage Collection – Python’s automatic system that frees memory by removing unused objects

By the end of this tutorial, you’ll have a strong understanding of Python’s variable storage and memory management, helping you write more reliable and efficient code.
