Python's `del` isn't guaranteed to free the memory, that's what
we are discussing here: core.memory.GC.free /
In CPython (the default reference distribution), the Garbage
collection in Python is not guaranteed to run when you delete the
object - all del (or the object going out of scope) does is
decrement the reference count on the object. The memory used by
the object is not guaranteed to be freed and returned to the
processes pool at any time before the process exits. Even if the
Garbage collection does run - all it needs is another object
referencing the deleted object and the garbage collection won’t
free the object at all.
