Python is a bad example to talk about gc, because it uses different garbage collector than most of languages. It is also the primary reason why getting rid of GIL and retaing performance is so hard. Python uses reference counters and as soon as the reference count drops to 0 it immediately frees the object, so in a way it is more predictable. It has also a traditional GC and I guess that's what was mentioned you can disable it. The reason for it is that reference count won't free memory of there is a loop (e.g. object A references B and B references A, in that case both have reference count 1 even though nothing is using them), do that's where the traditional GC steps in.
