如何用python函数来实现石头剪刀布效果

import random

number = 1

yin_number= 0

shu_number = 0

while number <= 3:

if shu_number == 2 or yin_number == 2:

break

user = int(input('注（0代表石头、1代表剪刀、2代表布）好兄弟请出拳：'))

if user > 2:

print('请认真注意游戏规则噢！不能出大于2数字')

else:

data = ['石头', '剪刀', '布']

com = random.randint(0, 2)

print("您出的是{}，我出的是{}".format(data[user], data[com]))

if user == com:

print('平局')

continue

elif (user == 0 and com == 1) or (user == 1 and com == 2) or (user == 2 and com == 0):

print('恭喜，你赢了')

yin_number += 1

else:

print('遗憾，你输了')

shu_number += 1

num += 1
