Python之random库的常用函数有哪些

import random

ran_num1 = random.random()
ran_num3 = random.randint(1, 6)
print("我是第一次随机结果：")
print(ran_num1)
print(ran_num3)
time.sleep(3)
print("我是第二次随机结果：")
print(ran_num1)
print(ran_num3)

    print(num)

#randrange

#sample

a = 0
while a < 5:
    num = random.sample(s, 1)
    a += 1
    print(num)
