random.rand(100_000_000) 当要计算a**5 + 2 * b这个表达式的结果时,一般会有两个办法: 一种是Numpy的向量化计算的方式,使用两个临时数组分别存放a**5和2*b的结果。 In: %timeit a**5 + 2 * b Out:2.11 s ± 31.1 ms per loop (mean ± std. dev. of 7 runs, 1 loop each) 此时你的...
Let’s see how we can use the random choice function to carry out perhaps the simplest random process – the flip of a single coin. 让我们看看如何使用随机选择函数来执行可能是最简单的随机过程——抛一枚硬币。 I’m first going to import the random library. 我首先要导入随机库。 So I type ...

Perhaps the terms “random” and “deterministic” seem like they cannot exist next to each other. To make that clearer, here’s an extremely trimmed down version of random() that iteratively creates a “random” number by using x = (x * 3) % 19. x is originally defined as a seed ...
