Memory Management in Python

Python automatically manages memory using reference counting and garbage collection. Understanding this helps write efficient and bug-free programs.

How Python Manages Memory

Reference Counting

a = []
b = a
print(id(a) == id(b))

Garbage Collection

Python removes unused objects automatically.

import gc
print(gc.collect())

Common Memory Issues

✔ Circular references
✔ Large objects in loops
✔ Global variables
📝 Practice: Track object references using sys.getrefcount()
