Parameters-----seed : array_like, int, optional Random seed initializing the PRNG. @DSM yes I have and you are apparently 100% correct. import numpy as np # output random float value out_val = np. NumPy - Array From Numerical Ranges. which would return an array of 50 random non-unique floats (ie: repetitions are allowed) uniformly distributed in the range [0.5, 13.3]. in the interval [low, high).. Syntax : numpy.random.randint(low, high=None, … Parameter of the distribution, >= 0 and <=1. How to explain why we need proofs to someone who has no experience in mathematical thinking? It is better to use numpy parameters (low, high, size, ..etc), and for the record to sample integers it's. The random module in Numpy package contains many functions for generation of random numbers. Size was not completely clear and link does not work. What guarantees that the published app matches the published open source code? Not just integers, but any real numbers. What should I do when I have nothing to do at the end of a sprint?
