Numpy’s random number routines produce pseudo random numbers using combinations of aBitGeneratorto create sequences and aGeneratorto use those sequences to samplefrom different statistical distributions: BitGenerators: Objects that generate random numbers. These are typically unsigned integer words filled ...

random.triangular(low, high, mode) Therandom.triangular()function returns a random floating-point number N such thatlower <= N <= upperand with the specified mode between those bounds. The default value of a lower bound is ZERO, and the upper bounds are one. Moreover, the peak argument ...
random.randrange的函数原型为:random.randrange([start], stop[, step]),从指定范围内,按指定基数递增的集合中 获取一个随机数。如:random.randrange(10, 100, 2),结果相当于从[10, 12, 14, 16, ... 96, 98]序列中获取一个随机数。random.randrange(10, 100, 2)在结果上与 random.choice(range(10,...
