如何修复此代码以处理测验中的正确答案

Question

我正在进行我的 NEA 评估，但我似乎无法在此处修复这段代码。该代码提供了艺术家姓名（在本例中为 BTS）和歌曲的首字母（F 代表 Fire）。当我输入 Fire 时，它​​显示不正确。

不完全确定在这里写什么作为背景。这是我第一次在 Python 上尝试这个。我在这里尝试了一些小改动，但无济于事。

file =  open("artistname.txt", "r")
artist = file.readline()
file.close()#opens file, reads it into artist variable and closes

file = open("songName.txt", "r")
song = file.readline()
file.close()#opens file, reads it into song variable and closes

score = 0
for round in range(len(artist)):
    print(artist)
    songInitial = song[:1]
    print(songInitial)#prints first initial
    if input() == song:
        print("Correct: +3 points")
        score = score + 3#adds 3 to score
        print("Score = ", score)#prints score
    else:
        print("Incorrect, try again")
        if input() == song:#allows second chance
            print("Correct: +1 point")
            score = score + 1#adds 1 to score
            print("Score = ", score)#prints score
        else:
            print("Incorrect, game over.")
            print("Score = ", score)#prints score
            break#ends code

我希望当我输入 Fire 时输出为“正确：+3 分”，并且只有在我输入错误答案时才给我第二次机会，然后在我第二次输入错误时结束游戏。相反，无论我输入什么，它都会重复错误，直到游戏结束。

如果你的artists.txt 看起来像这样：

BTS
BlackPink
Twice
(G)I-dle
BigBang
BTS
CLC
Twice
Blackpink
CLC
Mamamoo
Mamamoo
Red-Velvet
Twice
BTS
BlackPink
Twice
CLC
Red-Velvet
(G)I-dle

你的songs.txt 看起来像这样：

Fire
Stay
Fancy
Senorita
Fantastic-Baby
Idol
Me
TT
Forever-Young
No
Gogobebe
Egotistic
Zimzalabim
Yes-or-Yes
Dionysus
Kill-This-ove
Knock-Knock
Hobgoblin
Peekaboo
Latata

那么您需要做的不仅仅是file.readline()。 readline 只从文件中读取一行。如果您的文件真的只有一行长（所有艺术家/歌曲都用空格分隔），那么readline 可以工作 - 不过我不建议您像这样构建数据。我至少会把每个艺术家/歌曲放在一个单独的行上，就像我上面展示的那样。如果您只有一个文件，例如 .csv（逗号分隔值）文件，那就更好了，其中艺术家和歌曲明确配对在一起。

此代码假定您有两个文件，其中每个艺术家/歌曲都在单独的行中：

with open("artists.txt", "r") as file:
    artists = file.read().splitlines()

with open("songs.txt", "r") as file:
    songs = file.read().splitlines()

score = 0

# The amount of points you can earn for a given attempt
# You earn three points if you guess correctly on your first attempt
# You earn 1 point if you guess correctly on your second attempt
attempt_points = [3, 1]
max_attempts = len(attempt_points)

for artist, song in zip(artists, songs):
    song_initial = song[0]
    print("The artist is \"{}\" and the song's title begins with '{}'.".format(artist, song_initial))

    for current_attempt, points in enumerate(attempt_points, start=1):
        user_input = input("Enter your guess ({} attempt(s) remaining): ".format(max_attempts-current_attempt+1))

        if user_input == song:
            print("Correct: +{} points".format(points))
            score += points
            break
        elif current_attempt < max_attempts:
            print("Incorrect: Try again.")
    else:
        print("Game over.")
        break
    print("Score: {}".format(score))

else:
    print("Congratulations! You've managed to guess all songs correcly!")

print("Your total score is {}.".format(score))
