I'd say you can. The information about the Mersenne Twister underlying
the module's functions isn't marked as "CPython Implementation Note",
so I would expect that every Python implementation will provide a
minimum of 53-bit precision. (It does have the feeling of an
implementation detail though; is there a guarantee that two Pythons
will generate the same sequence of numbers from the same seed?)
