What is garbage collection in Python?
Garbage collection in Python is a mechanism for automatically managing memory by reclaiming memory occupied by objects that are no longer in use.
How does Python's garbage collection work?
Python primarily uses reference counting to track object usage, and it also has a cyclic garbage collector to handle reference cycles.
Can you explain reference counting?
Sure! Reference counting keeps track of the number of references to each object. When an object's reference count drops to zero, it is automatically deallocated.
What are reference cycles and how does Python handle them?
Reference cycles occur when two or more objects reference each other, preventing their reference counts from reaching zero. Python's cyclic garbage collector identifies and collects these cycles.
