random.BitGenerator.random_raw(self, size=None)#

Return randoms as generated by the underlying BitGenerator

sizeint or tuple of ints, optional

Output shape. If the given shape is, e.g., (m, n, k), then m * n * k samples are drawn. Default is None, in which case a single value is returned.

outputbool, optional

Output values. Used for performance testing since the generated values are not returned.

outuint or ndarray

Drawn samples.


This method directly exposes the raw underlying pseudo-random number generator. All values are returned as unsigned 64-bit values irrespective of the number of bits produced by the PRNG.

See the class docstring for the number of bits returned.
