import random

import string

# 随机整数:

print random.randint(1,50)

# 随机选取0到100间的偶数:

print random.randrange(0, 101, 2)

# 随机浮点数:

print random.random()

print random.uniform(1, 10)

# 随机字符:

print random.choice('abcdefghijklmnopqrstuvwxyz!@#$%^&*()')

# 多个字符中生成指定数量的随机字符:

print random.sample('zyxwvutsrqponmlkjihgfedcba',5)

# 从a-zA-Z0-9生成指定数量的随机字符:

ran_str = ''.join(random.sample(string.ascii_letters + string.digits, 8))

print ran_str

# 多个字符中选取指定数量的字符组成新字符串:

prin ''.join(random.sample(['z','y','x','w','v','u','t','s','r','q','p','o','n','m','l','k','j','i','h','g','f','e','d','c','b','a'], 5))

# 随机选取字符串:

print random.choice(['剪刀', '石头', '布'])

# 打乱排序

items = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]

print random.shuffle(items)
