由于需要电脑随机出拳，所以我们这里导入随机数模块，具体代码：
import random
然后用input 代码和用户交互，让用户选择出 剪刀 石头或者布
player = input("请输入要出的选项:剪刀(1)/石头(2)/布(3)")
2
对玩家出拳进行判断，我们这里用 1 代表了 剪刀 2 代表石头 3 代表布 所以我们限制玩家只能出 这三个数字，输入其他字符 则提示玩家出拳错误
if player.isdigit() and int(player) >= 1 and int(player) <= 3:
else:
print("出拳有误")
3
下面在用户输入正确的情况下 写入判断代码，首先把用户输入的数字转换成整数类型，以及将电脑随机数代码完善
player = int(player)
cpu = random.randint(1, 3)
4
继续用if判断，将电脑和用户输入的数字判断成拳头，代码如下：
if player == 1:
player1 = "剪刀"
if player == 2:
player1 = "石头"
if player == 3:
player1 = "布"
if cpu == 1:
cpu1 = "剪刀"
if cpu == 2:
cpu1 = "石头"
if cpu == 3:
cpu1 = "布"
print("玩家出拳为:", player1, "电脑出拳为:", cpu1)
判断最后打印出双方出拳的结果
5
然后我们进行胜负条件的判断，我们先写上当用户胜利时候的情况，具体代码如下：
if (player == 1 and cpu == 3) \
or (player == 2 and cpu == 1) \
or (player == 3 and cpu == 2):
print("玩家胜利")
6
按照同样的判断方法，判断出电脑胜利和平局的结果：
if (player == 1 and cpu == 2) \
or (player == 2 and cpu == 3) \
or (player == 3 and cpu == 1):
print("电脑胜利")
if (player == 1 and cpu == 1) \
or (player == 2 and cpu == 2) \
or (player == 3 and cpu == 3):
print("平局")

经过以上代码，我们基本完成了整个游戏的过程，下面运行一下看效果：

整体代码总结：
import random
player = input("请输入要出的选项:剪刀(1)/石头(2)/布(3)")
if player.isdigit() and int(player) >= 1 and int(player) <= 3:
player = int(player)
cpu = random.randint(1, 3)
if player == 1:
player1 = "剪刀"
if player == 2:
player1 = "石头"
if player == 3:
player1 = "布"
if cpu == 1:
cpu1 = "剪刀"
if cpu == 2:
cpu1 = "石头"
if cpu == 3:
cpu1 = "布"
print("玩家出拳为:", player1, "电脑出拳为:", cpu1)
#
if (player == 1 and cpu == 3) \
or (player == 2 and cpu == 1) \
or (player == 3 and cpu == 2):
print("玩家胜利")
if (player == 1 and cpu == 2) \
or (player == 2 and cpu == 3) \
or (player == 3 and cpu == 1):
print("电脑胜利")
if (player == 1 and cpu == 1) \
or (player == 2 and cpu == 2) \
or (player == 3 and cpu == 3):
print("平局")
else:
print("出拳有误")
