random_integers(low[, high, size]) 返回随机的整数,位于闭区间 [low, high]。 Notes To sample from N evenly spaced floating-point numbers between a and b, use: a + (b - a) * (np.random.random_integers(N) - 1) / (N - 1.) Examples >>> np.random.random_integers(5) 4 >>> t...

Not only doesnp.random.permutationhelp in shuffling arrays in ways thatnp.random.shufflecannot, But it can also achieve the same results thatshuffleproduces on lists and arrays. In this section, we will learn the various similarities and differences between the two methods. ...

The global random seed in NumPy affects a wide range of functions that generate random numbers or perform random operations. Here are examples of some of these functions. rand Generates random floats between 0 and 1: import numpy as np
