为什么分数显示不正确？

问题是在将分数增加之前将分数存储在变量中，因此您总是落后1个游戏。确保分数始终正确的最简单方法是创建一个函数来获取分数，如下所示：

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

这样可以确保始终使用最新的用户和comp得分值。使用这个代码变成...

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")
