PEP 442 describes the situation with good detail, including how it was in Python 2 and how Python 3 improves on it:

I know Haskell does: https://hackage.haskell.org/package/base-4.9.1.0/docs/Foreig... I'm not sure finalizers make sense without a guarantee they will eventually be called. But Haskell, for example, makes no guarantees about when it will be called, between the moment the last reference is lost and the moment the program exits.

Python seems to, too: https://docs.python.org/3/library/weakref.html, "When the program exits, each remaining live finalizer is called unless its atexit attribute has been set to false. They are called in reverse order of creation."
