WebMar 8, 2016 · Almost all module functions depend on the basic function random (), which generates a random float uniformly in the semi-open range [0.0, 1.0). Python uses the Mersenne Twister as the core generator. It produces 53-bit precision floats and has a period of 2**19937-1. The underlying implementation in C is both fast and threadsafe. What is the best way to generate pseudo uniform random numbers (a double in [0, 1)) that is: Cross platform (ideally with same same sample sequence) Thread safe (explicit passing of the mutated state of the prng or using a thread-local state internally) Without GIL lock. Easily wrappable in Cython.
