If you're talking about Python objects, that's not necessarily
true -- there's no requirement that a Python object occupy a
contiguous range of machine addresses. In CPython, many don't,
e.g. strings.

Even for those that do, it's a range of *virtual* addresses,
which doeesn't necessarily correspond to contiguous physical
addresses, e.g. if it crosses a page boundary.
