编写带积分统计的Python石头剪刀布游戏时积分重置为0的问题排查求助

嘿，我来帮你搞定这个积分总是重置的问题！你的代码里主要有两个核心问题导致积分无法正确累加，咱们一步步拆解：

问题1：函数参数传递的坑 #

Python里整数属于不可变类型，当你把points和oppoints作为参数传给result函数时，函数内部修改的只是这两个变量的局部副本，根本不会影响外部定义的全局变量。也就是说，你在函数里points +=1的时候，改的只是函数内部的临时变量，外面的points还是原来的值，看起来就像是每次都重置成0了。

问题2：重复调用result函数的逻辑错误 #

不管玩家选了石头、布还是剪刀，你每次都调用三次result函数：

result("rock","scissors","papper",points,oppoints) 
result("papper","rock","scissors",points,oppoints) 
result("scissors","papper","rock",points,oppoints) 

这会导致同一个回合里重复判断三次，逻辑完全混乱，就算参数传递没问题，积分也会算错。

修正后的代码 #

我把这两个问题都修复了，还修正了拼写错误（"papper"改成了正确的"paper"），你可以直接用：

import random 

points = 0 
oppoints = 0 
opt = ["rock", "paper", "scissors"] 
ans = "yes" 

# 修改函数，让它返回更新后的积分
def result(name, win, loose, current_points, current_oppoints, cho, opp): 
    if cho == name: 
        if opp == win: 
            current_points += 1 
            print("congrats you got a point") 
        elif opp == loose: 
            current_oppoints += 1 
            print("you lost the point") 
        else : 
            print("its a tie no one gets a point") 
    return current_points, current_oppoints  # 返回更新后的积分

while ans == "yes" : 
    # 先重置积分，准备新一局
    points = 0
    oppoints = 0
    while points < 2 and oppoints < 2 :  # 改成and，一方到2分就结束对局
        cho = input("rock paper scissors: ").lower()  # 转小写避免大小写问题
        # 验证输入是否合法
        while cho not in opt:
            print("Invalid input! Please enter rock, paper, or scissors.")
            cho = input("rock paper scissors: ").lower()
            
        opp = random.choice(opt) 
        print("opponent: " + opp) 
        
        # 根据玩家选择，只调用对应的判断函数
        if cho == "rock":
            points, oppoints = result("rock", "scissors", "paper", points, oppoints, cho, opp)
        elif cho == "paper":
            points, oppoints = result("paper", "rock", "scissors", points, oppoints, cho, opp)
        elif cho == "scissors":
            points, oppoints = result("scissors", "paper", "rock", points, oppoints, cho, opp)
            
        print("Your points:", points) 
        print("Opponent's points:", oppoints) 
        
    if points > oppoints : 
        print("you win!!") 
    else: 
        print("you lost :(") 
    ans = input("wanna play again?? ").lower() 

print("good bye")

额外优化点说明 #

• 把循环条件从points < 2 or oppoints < 2改成了points < 2 and oppoints < 2，这样只要有一方先拿到2分，就结束当前对局，更符合常规规则。
• 增加了输入验证，避免玩家输入错误的内容导致逻辑出错。
• 把输入转成小写，玩家输入Rock、PAPER这类大小写混合的内容也能正常识别。
