python生成随机数、随机字符串

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))

print random.shuffle(items)
