为什么分数显示不正确？

Question

我还是python的初学者，所以我决定做一个石头游戏。出于某种原因，当用户或计算机获胜时，直到下一轮才给他们一个分数。

import random
games = int(input("")) #how many games
usersc = 0
compsc = 0
for x in range(games):
    score = (str(usersc) + "-" + str(compsc))
    user = input("") #ROCK, PAPER, SCISSORS
    comp = random.randint(0,2)
    if user == 'ROCK':
        if comp == 0:
            print("tie " + score)
        elif comp == 1:
            compsc += 1
            print("loss " + score)
        else:
            usersc += 1
            print("win " + score)
    elif user == 'PAPER':
        if comp == 0:
            usersc += 1
            print("win " + score)
        elif comp == 1:
            print("tie " + score)
        else:
            compsc += 1
            print("loss " + score)
    elif user == 'SCISSORS':
        if comp == 0:
            compsc += 1
            print("loss " + score)
        elif comp == 1:
            usersc += 1
            print("win " + score)
        else:
            print("tie " + score)
    else:
        print("try again")

if compsc > usersc:
    print("loss")
elif usersc > compsc:
    print("win")
else:
    print("tie")

例如，当计算机赢了，它应该说输了 0-1 却说输了 0-0，但是下一轮它会说输了 0-1。任何帮助将不胜感激。

Answer 1

当您正在打印 loss+score 或 win+score,

首先将分数更新为score = (str(usersc) + "-" + str(compsc))，然后打印它。

Answer 2

问题是你在增加分数之前将分数存储在变量中，所以你总是落后 1 场比赛。确保分数始终正确的最简单方法是创建一个函数来获得这样的分数...

def get_score():
    return str(usersc) + "-" + str(compsc)

这将确保始终使用最新的用户和竞争分数值。使用此代码变为...

import random

games = int(input("")) #how many games
usersc = 0
compsc = 0

def get_score():
    return str(usersc) + "-" + str(compsc)

for x in range(games):
    user = input("") #ROCK, PAPER, SCISSORS
    comp = random.randint(0,2)
    if user == 'ROCK':
        if comp == 0:
            print("tie " + get_score())
        elif comp == 1:
            compsc += 1
            print("loss " + get_score())
        else:
            usersc += 1
            print("win " + get_score())
    elif user == 'PAPER':
        if comp == 0:
            usersc += 1
            print("win " + get_score())
        elif comp == 1:
            print("tie " + get_score())
        else:
            compsc += 1
            print("loss " + get_score())
    elif user == 'SCISSORS':
        if comp == 0:
            compsc += 1
            print("loss " + get_score())
        elif comp == 1:
            usersc += 1
            print("win " + get_score())
        else:
            print("tie " + get_score())
    else:
        print("try again")

if compsc > usersc:
    print("loss")
elif usersc > compsc:
    print("win")
else:
    print("tie")
