How Python Memory management works Part 2|Generational Garbage collection|Python Interview Questions

Описание: Generational garbage collection is a cycle detection based algorithm which is used by Python garbage collector in order to deal with 'Reference cycles', a situation which the reference counting algorithm can not resolve.

In the last video of this particular topic, we discussed about the Reference counting algorithm as a way to manage memory in Python. Now in this video, we are going to see the limitations of reference counting and learn how python uses the Generational garbage collection algorithm to tackle the reference cycle problem.
