创建随机数组

import numpy as np

arr1 = np.random.random(5)
print("\n" + "0-1均匀分布的浮点型随机数组：" + str(arr1))

#(100-60)相当于把 [0, 1)区间映射到 [0, 40)区间。
arr2 = (100-60) * np.random.random((3,3)) + 60
print("\n" + "60-100均匀分布的浮点型随机数组：" + str(arr2))

arr3 = np.random.randint(10,100,(1,15))
print("\n" + "整数型随机数组:" + str(arr3))

arr4 = np.random.normal(0,1,(2,3))
print("\n" + "服从正态分布的随机数组:" + str(arr4))
