random模块常用函数: from random import * # Random float: 0.0 <= x < 1.0 random() # Random float: 2.5 <= x < 10.0 uniform(2.5, 10.0) # Integer: 0 <= x <= 9 randrange(10) # Even integer from 0 to 100 inclusive randrange(0, 101, 2) # Single rando
numpy.random模块中常用函数解析 numpy.random模块官方文档 1. numpy.random.rand(d0, d1, ..., dn)Create an array of the given shape and populate it with random samples from a uniform distribution over [0, 1)按照给定形状产生一个多维数组,每个元素在0到1之间注意: 这里定义数组形状时,不能采用tuple import numpy
sample(序列a,n) 功能:从序列a中随机抽取n个元素,并将n个元素生以list形式返回. 例: from random import randint, sample date = [randint(10,20) for _ in range(10)] c = sample(date, 5) print(c) 输出:[12, 17, 10, 12, 17] randint(10,20) for _ in range(10):从10~20间随机抽取10个数:
