python脚本：石头剪刀布

代码如下（示例）：

# coding=utf-8
import random

# 用户出拳，1=石头；2=剪刀；3=布
player = int(input("请出拳：1=石头；2=剪刀；3=布："))

if player != 1 and player != 2 and player != 3:
    print('请好好出拳，别搞事')
    exit(0)

# 电脑随机出拳
ai = random.randint(1, 3)

if player == 1:
    player_c = '石头'
elif player == 2:
    player_c = '剪刀'
else:
    player_c = '布'

if ai == 1:
    ai_c = '石头'
elif ai == 2:
    ai_c = '剪刀'
else:
    ai_c = '布'

print('玩家出拳：%s；ai出拳：%s' % (player_c, ai_c))

# 判断胜负

if ((player == 1 and ai == 2)
        or (player == 2 and ai == 3)
        or (player == 3 and ai == 1)):
    print('电脑弱爆了')
elif ((player == 1 and ai == 3)
      or (player == 2 and ai == 1)
      or (player == 3 and ai == 2)):
    print('我不服，再来一次')
else:
    print('不要走，决战到天亮')
