如何使用 Numpy 编写程序来生成和打印 0 和 1 之间的 5 个随机数

Question

How to write a program using Numpy to generate and print 5 random number between 0 and 1

Answer 1

import numpy as np
numbers = np.random.rand(5)
print(numbers)

np.random.rand will produce a sample from the uniform distribution over [0,1]

If you want to generate numbers from a different interval, let's say [a,b], you can use:

import numpy as np

a = 2
b = 4
numbers = a + np.random.rand(5)*(b-a)
print(numbers)
