猜拳游戏

前几天看到这个题目，就在写，但是不是知道为什么老是出错，今天起来再一些了一遍测试就对了不知道为什么！

#!/usr/bin/env python
#coding:utf-8

import random

winrule = ['stone','scissors','cloth',]
guize = [['cloth','stone'],['stone','scissors'],['scissors','cloth']]
i = 0
time = 3
people_win_time = 0
people_lost_time = 0
while i < time:
             i += 1
             computer = random.choice(winrule)
             print computer
             people = raw_input('People select: ')
             if computer == people:
                          print 'draw'
             else:
                          if [computer,people] in guize:
                                       print 'Bad! YOU LOST!'
                                       people_lost_time += 1
                          else:
                                       print 'God! YOU WIN!'
                                       people_win_time += 1
print 'people_win_time : %s,people_lost_time : %s' %(people_win_time,people_lost_time)
if people_win_time > people_lost_time:
             print 'you win!'
else:
             if people_win_time == people_lost_time:
                          print 'draw'
             else:
                          print 'you lost'

还有没有解决的问题：

　　1、如果出现了赢了的次数和输了的次数一样的话想重新再来一遍，或者输入exit直接退出不玩了，今天没有时间就没有写了

　　2、如果输入的不是stone,scissors,cloth，则提示要输入stone,scissors,cloth。
