Both cpython random and numpy.random use Mersenne Twister.

Both cpython random and numpy.random use /dev/(u)random on UNIX and CryptGenRandom on Windows for entropy.

Cpython allows to use Wichman Hill as an alternative PRNG, numpy does not (however you can use random.WichmanHill to fill a previously allocated array).
