#random模块
import random
import string
print(random.randint(10,100))   
print(random.randrange(10,100,5))  #数字5是步长
print(random.random())  #返回随机浮点数
print(random.choice('asdasdafafaf'))   #返回字符串的随机一个
print(random.sample(range(1,31),5))     #从多个对象中随机返回指定个对象
print(string.digits + string.ascii_lowercase)
print(''.join(random.sample((string.digits + string.ascii_lowercase),5)))        #随机生成网站验证码
a = list(range(10))
random.shuffle(a)   #打乱原有列表的顺序
print(a)
