How does Python manage memory and garbage collection?

Q: How does Python manage memory and garbage collection?

CPython uses **reference counting** — an object is freed when its refcount hits zero — plus a cyclic **garbage collector** to reclaim reference cycles. Memory is managed in private heaps with object pools for small objects. You rarely manage it manually but should avoid lingering references and cycles.
