equidistributed uniform pseudorandom number generator", ACM Transactions on Modeling and Computer Simulation Vol. 8, No. 1, January pp.3--30 1998. 簿记功能¶ random.seed(a=None, version=2)¶ 1. 初始化随机数生成器。 如果a 被省略或为 None ,则使用当前系统时间。 如果操作系统提供随机源,则...
如果想将其存储,可以使用一个变量: from random import * x = randint(1, 100) # Pick a random number between 1 and 100. print x 1. 2. 3. 1到10之间的随机数 要生成一个1到10之间的随机浮点数,可以使用uniform() 函数: from random import * print uniform(1, 10) 1. 2. 从列表中选择一个...
