python 打乱一个数组的简单方法

#coding:utf-8
import random
def f(x,y):return random.randint(1,2)*2-3

a=range(10)
print a
#[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
a.sort(f)
print a
#[3, 1, 8, 5, 2, 9, 0, 4, 6, 7]
#随机性还不错

import random
a = range(10)
print a
#[0,1,2,3,4,5,6,7,8,9]

random.shuffle(a)
print a
#[3, 1, 8, 5, 2, 9, 0, 4, 6, 7]
