Python 我正在创作一个音乐测验，但似乎在测验中的随机点上得到同样的错误。

我的代码旨在：

在外部文件中存储歌曲名称和艺术家的列表

从文件中选择一首歌曲，显示艺术家和歌曲标题每个单词的第一个字母

允许用户最多两次猜测歌曲名称，如果第二次猜错歌曲，则停止游戏

如果猜测是正确的，根据猜测的次数将分数加到玩家的分数上

歌曲和艺术家名称将从阵列/外部文件中删除

显示游戏结束时玩家的点数

目前，我的代码在回答问题和给出错误时被卡住： ChosenSong=（歌曲[随机编号]） 索引器：列表索引超出范围

无论如何，修复这将是伟大的

当前我的代码如下所示：

import random
points = 0
x = 1

SongArtists = open("Songs and Artists.txt","r")
ReadValues = SongArtists.readline()
songs = []
artists = []

while len(songs) < len(ReadValues):
    field = ReadValues.split(",")
    songTitle = field[0]
    artistName = field[1]
    songs.append(songTitle)
    artists.append(artistName)

    ReadValues = SongArtists.readline()




print("")

from random import *

while x == 1:

    RandomNumber = (randint(0,len(songs)))
    RandomNumber = RandomNumber + 1
    ChosenSong = (songs[RandomNumber])
    print("")
    print(artists[songs.index(ChosenSong)])

    print("")

    Field = ChosenSong.split(" ")

    lenOfField = len(Field)

    if lenOfField == 1:

        letter = Field[0]
        print(letter[ : 1])
        songs.pop(RandomNumber)
        artists.pop(RandomNumber)



    elif lenOfField == 2:
        letter = Field[0]      
        secondletter = Field[1]
        print((letter[ : 1])+" "+(secondletter[ : 1]))
        songs.pop(RandomNumber)
        artists.pop(RandomNumber)


    elif lenOfField == 3:
        letter = Field[0]       
        secondletter = Field[1]
        thirdletter = Field[2]
        print((letter[ : 1])+" "+(secondletter[ : 1])+" "+(thirdletter[ : 1]))
        songs.pop(RandomNumber)
        artists.pop(RandomNumber)




    elif lenOfField == 4:
        letter = Field[0]       
        secondletter = Field[1]
        thirdletter = Field[2]
        fourthletter = Field[3]
        print((letter[ : 1])+" "+(secondletter[ : 1])+" "+(thirdletter[ : 1])+" "+(fourthletter[ :1]))
        songs.pop(RandomNumber)
        artists.pop(RandomNumber)



    elif lenOfField == 5:
        letter = Field[0]       
        secondletter = Field[1]
        thirdletter = Field[2]
        fourthletter = Field[3]
        fifthletter = Field[4]
        print((letter[ : 1])+" "+(secondletter[ : 1])+" "+(thirdletter[ : 1])+" "+(fourthletter[ :1])+" "+(fifthletter[ :1]))
        songs.pop(RandomNumber)
        artists.pop(RandomNumber)






    print("")    

    guess = input("What is your guess : ").title()

    if guess == ChosenSong:
        points += 3
        print("Correct, You get 3 points! You're score is", points)

    else:

        print("")

        print("Wrong, If you get this wrong You Lose ")

        secondguess = input("What is your guess : ")

        if secondguess == ChosenSong:
            points += 1
            print("Correct, You get 3 points! You're score is", points)        

        else:
            print("Game Over, You Scored " + str(points) + " points")

            ScoreFile = open("Scores.txt","a")
            ScoreFile.write(str(points))
            ScoreFile.write("\n")

            break

随机导入
分数=0
x=1
SongArtists=open（“Songs and Artists.txt”、“r”）
ReadValues=SongArtists.readline（）
歌曲=[]
艺术家=[]
而len（歌曲）

此处：

RandomNumber = (randint(0,len(songs)))
RandomNumber = RandomNumber + 1

如果您的随机数在初始化时等于len（歌曲），则它已超出

歌曲

范围

---

根据randint（a，b），返回

一个随机整数N，这样a问题在于你的随机歌曲机制。randint（）返回一个介于范围（包括极值）之间的数字。所以你基本上得到了一个介于1和len（歌曲）+1之间的随机数，这是你不想要的，因为索引以len（歌曲）-1结尾

所以你应该做些什么

RandomNumber = random.randint(0, len(songs)-1)
ChosenSong = songs[RandomNumber]

你应该看看<代码> RANTENT <代码>如何使用它的边界，并且在选择一个随机索引之后，肯定重新考虑添加一个。考虑使用<代码>随机。选择< /C> >选择一个集合的一个随机元素，而不是手动生成索引。
RandomNumber=RandomNumber+1
会导致RandomNumber等于len（歌曲）。但是歌曲的最高索引是len（songs）-1，因为数组索引从零开始。如果它等于
len（songs）
，则在将1添加到它之前，它已经超出了范围！
RandomNumber = random.randint(0, len(songs)-1)
ChosenSong = songs[RandomNumber]
