numpy.random.randint(low, high=None, size=None, dtype='l')Return random integers from low (inclusive) to high (exclusive). 【例】若high不为None时,取[low,high)之间随机整数,否则取值[0,low)之间随机整数。 import numpy as np np.random.seed(20200614) x = np.random.randint(2, size=10) p...
Usingrandrange()andrandint()functions of a random module, we can generate a random integer within a range. In this lesson, you’ll learn the followingfunctions to generate random numbers in Python. We will see each one of them with examples. functions to generate random numbers Also, See: P...

除了random方法用于生成随机浮点数,integers方法用于生成随机整数,还有一个bytes方法用于生成原始的随机字节。这些方法中的每一个都调用底层BitGenerator实例上的相关方法。这些方法还允许生成的数字的数据类型进行更改,例如,从双精度到单精度浮点数。 还有更多… Generator类上的integers方法通过添加endpoint可选参数,结合了...
