python语言里random库用法详解

random.random()

​

r.random()

random.uniform(min,max)

​

​ min,max可以为小数

r.uniform(10.78, 12.5)

random.randint(min,max)

​

r.randint(12, 56)

random.choice(元组/列表/range()/字符串)

​

(r.choice(tuple1)

random.randrange(min,max,tap_num)

​

print(r.randrange(0, 60, 3))

random.sample(元组/列表/字符串/range(), num)

​

print(r.sample(names, 2))

random.shuffle(可变变量)

​

r.shuffle(names)

以上变换中，字典类型均不可以！

import random as r
names = [\'国成\', \'翼飞\', \'柱鼎\', \'宝明\', \'清源\', \'超\', \'战国\', \'政辉\',
         \'贤\', \'紫洋\', \'轶康\', \'泳\', \'博通\', \'显伯\', \'嘉毓\', \'思琴\', \'锶溢\']
tuple1 = (1, 2, 3, 4, 5)
dict1 = {
    \"math\": 578,
    \'english\': 980,
    \"chinese\": 789,
    \"message\": \"这是一则非常重要的消息\",
    \"password\": \"请记好你的密码！\"
}
print(r.random(), r.uniform(10.78, 12.5), r.randint(12, 56))
print(r.choice(tuple1), r.choice(range(0, 5)), r.choice(names))
print(r.randrange(0, 60, 3))
print(r.sample(names, 2))
r.shuffle(names)
print(names)
