BitGenerators: Objects that generate random numbers. These are typically unsigned integer words filled with sequences of either 32 or 64 random bits. Generators: Objects that transform sequences of random bits from a BitGenerator into sequences of numbers that follow a specific probability distributio...
Almost all module functions depend on the basic functionrandom(), 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 implement...
