 CPython does use garbage collection, as far as I know.
 

AFAIK CPython uses reference counting, i.e. basically the same as C++ std::shared_ptr (except that it does not need to be thread-safe).
With reference counting one only knows how many pointers there are to a given heap block, but not where they are, so heap compaction would not be straightforward.
Python also has zillions of extensions written in C or C++ (all of AI related work for example), so having e.g. heap compaction of Python objects only might not be worth of it.
