![]() The Mersenne Twister is one of the most extensively tested random number generators in existence. The underlying implementation in C is both fast and threadsafe. It produces 53-bit precision floats and has a period of 219937-1. The Gaussian values are drawn from a standard Gaussian distribution this is a distribution that has a mean of 0. Python uses the Mersenne Twister as the core generator. This function takes a single argument to specify the size of the resulting array. ![]() > import numpy as np > randnums np.random.

If you want to create arrays of random numbers then why not use a library that provides an API specifically for that You can test yourself to see that numpy is 10x faster for large arrays: Python 2.7 on Linux: python -m timeit -s import random - random. rand Convenience function that accepts dimensions as input, e.g., rand (2,2) would generate a 2-by-2 array of floats, uniformly distributed over 0, 1). This page allows you to generate random integers using true randomness, which for many purposes is better than the pseudo-random number algorithms typically. An array of random Gaussian values can be generated using the randn() NumPy function. Below is the code to create a random 4 x 5 array in Python. ![]()
