请用python编写程序。 人和机器猜拳的游戏写成一个类。 有如下几个方法： 方法1：选择角色 1 Superman 2 Spiderman 3 Captain 方法2：角色猜拳 1剪刀 2石头 3布 ，玩家输入一个1-3的数字（注意判断是否超出此范围） 方法3：电脑出拳 随机产生1个1-3的数字，提示电脑出拳结果 方法4：角色和机器出拳对战，对战结束后，最后出示本局对战结果…赢…输,然后提示用户是否继续？按y继续，按n退出 最后结束的时候输出结果 角色赢几局 电脑赢几局，平局几次 游戏结束

好的，这是一个编程问题，我可以帮您解答。以下是您需要的代码，您可以在Python环境中运行它：

import random

class GuessGame:
def __init__(self):
self.player = ""
self.computer = ""
self.player_wins = 0
self.computer_wins = 0
self.ties = 0

def choose_character(self):
while True:
character = input("请选择一个角色：\n1. Superman\n2. Spiderman\n3. Captain\n输入角色代码：")
if character in ["1", "2", "3"]:
if character == "1":
self.player = "Superman"
elif character == "2":
self.player = "Spiderman"
elif character == "3":
self.player = "Captain"
break
else:
print("输入错误，请重新输入！")

def player_guess(self):
while True:
guess = input("请出拳：\n1. 剪刀\n2. 石头\n3. 布\n输入数字：")
if guess in ["1", "2", "3"]:
if guess == "1":
self.player = "剪刀"
elif guess == "2":
self.player = "石头"
elif guess == "3":
self.player = "布"
break
else:
print("输入错误，请重新输入！")

def computer_guess(self):
self.computer = random.choice(["剪刀", "石头", "布"])
print("电脑出拳：" + self.computer)

def play_round(self):
self.choose_character()
self.player_guess()
self.computer_guess()
if (self.player == "剪刀" and self.computer == "布") or \
(self.player == "石头" and self.computer == "剪刀") or \
(self.player == "布" and self.computer == "石头"):
self.player_wins += 1
print("你赢了！")
elif (self.computer == "剪刀" and self.player == "布") or \
(self.computer == "石头" and self.player == "剪刀") or \
(self.computer == "布" and self.player == "石头"):
self.computer_wins += 1
print("电脑赢了！")
else:
self.ties += 1
print("平局！")

def play_game(self):
print("欢迎玩猜拳游戏！")
while True:
self.play_round()
continue_game = input("继续游戏吗？（y/n）")
if continue_game.lower() != "y":
break
print("游戏结束！")
print("你赢了 " + str(self.player_wins) + " 次，电脑赢了 " + str(self.computer_wins) + " 次，平局 " + str(self.ties) + " 次。")

game = GuessGame()
game.play_game()

请注意，该代码已经包括了问题中所述的所有方法。如果您需要修改游戏规则或添加其他功能，可以基于该代码进行进一步的开发。祝您玩得愉快！
