python实现随机生成一张扑克牌

一副扑克牌包含4种花色，12个数值，1个小王，1个大王，实现随机生成一张牌

代码如下：

#coding=utf-8
import random

def poker():
    color = random.randint(0,4)
    huase = ['黑桃','红桃','方块','梅花','王']
    card = ['A','2','3','4','5','6','7','8','9','10','J','Q','K']

    if color in range(0,4):
        value = random.randint(0,12)
    elif color == 4:
        value = random.randint(0,1)
        if value==0:
            return "小王"
        if value==1:
            return "大王"
    else:
        return "错误的牌"

    return huase[color]+card[value]

if __name__ == '__main__':
    print poker()
