The reference implementation (CPython) does use reference counting, but that is not its only approach to garbage collection. "The default build implementation is a generational collector. The free-threaded build is non-generational; each collection scans the entire heap." https://devguide.python.org/internals/garbage-collector/ https://docs.python.org/3/library/gc.html (And as someone else pointed out, asyncio's event loop keeps only weak references to tasks, so the GC implementation doesn't really matter here.) |
