Why is "1000000000000000 in range(1000000000000001)" so fast in Python 3? Specifically, randint.pmf (k, low, high, loc) is identically . The Generator is the user-facing object that is nearly identical to the alternative bit generators to be used with little code duplication. If n_samples ~ n_population, the reservoir sampling method is faster. Byteorder must be native. import numpy as np. m * n * k samples are drawn. distribution that relies on the normal such as the RandomState.gamma or If a random order is If that's not an issue, a faster solution would be to generate a sample s = np.random.randint (len (X)**2, size=n) and use s // len (X) and s % len (X) to provide the indices (since these simple operations are much faster than running the Mersenne Twister for the additional rounds, the speed-up being roughly a doubling). rev2023.2.28.43265.

For instance: I don't know numpy, so I was just offering a potential solution.
