Memory Management

This concept deals with the way python manages memory, how it assigns memory, how it cleans memory and garbage collect.

An OS-specific virtual memory manager carves out a chunk of memory for the Python process.

Python uses a portion of the memory for internal use and non-object memory. The other portion is dedicated to object storage (your int, dict, and the like).

Heaps and Stack

These are the two major datastructure that is being used by any programming language for running the programs.

Heaps

Heaps are used for stroing data and objects in memory that are being referenced from stacks.

Stacks

These are used for mainly function calls and variables in the a particular scope.

Garbage Collection

Python interpretor keeps the reference count of all the variables, if reference count of any variable becomes 0. That variable is garbage collected.
