Python猜歌游戏代码故障修复及文件数据层级化展示咨询

问题概述 #

这是一款基于Python的猜歌游戏，程序从music文件中随机选取歌曲数据，玩家凭借歌手名和歌曲名单词首字母猜测歌名。目前存在两个问题：

• 玩家首次猜错后再答对，程序会直接终止，无法进入下一轮猜歌
• 需要实现文件数据的层级化排序展示

当前代码 #

import random
score = 0

# 玩家信息设置
username = input("Please enter a username:")
password = input("Please enter a password:")

# 玩家验证
player_usr = input("Enter your username")
player_pass = input("Enter your password")

if player_usr == username:
    if player_pass == password:
        start = True
    else:
        print("Acces denied. Wrong details.")
        start = False
else:
    print("Acces denied. Wrong details")
    start = False

# 主游戏循环
while start == True:
    t = True
    while t == True: 
        lines = open("music").read().splitlines()
        myline = random.choice(lines) # 从文件选歌
        chosensong = myline
    
        artist = chosensong.rsplit(",", 1)[1]
        print(artist) # 输出歌手名

        song = chosensong.rsplit(",",1)[0]
        for word in song.split():
            print(word[0]) # 输出歌名每个单词首字母
        t = False

    target = chosensong.rsplit(",",1)[0]
    guess = None
    guesses = 0 
    answer = input("Enter guess:")
    guess = answer.lower()
    
    # 答案验证与计分
    while guesses != 2:
        if guess == target:
            if guesses == 0:
                score = score + 3
                print("you were correct")
                break
            else:
                score = score + 1
                print("you were right")
                break
        else:
            print("please try again")
            guesses = guesses + 1
            answer = input("Enter guess:")
            guess = answer.lower()
            start = False

print(score)

一、猜歌流程终止问题修复 #

问题根源 #

在答错分支中错误设置了start = False，导致哪怕后续答对，主循环的start已经为False，直接终止游戏。同时存在大小写不匹配、文件重复读取的效率问题。

修复后的完整代码 #

import random
score = 0

# 玩家信息设置
username = input("请输入用户名:")
password = input("请输入密码:")

# 玩家验证
player_usr = input("输入你的用户名:")
player_pass = input("输入你的密码:")

start = False
if player_usr == username and player_pass == password:
    start = True
else:
    print("访问拒绝，账号信息错误")

# 提前读取所有歌曲数据，避免重复IO
with open("music", "r", encoding="utf-8") as f:
    all_songs = f.read().splitlines()

# 主游戏循环
while start:
    # 随机选歌
    chosensong = random.choice(all_songs)
    song_name, artist = chosensong.rsplit(",", 1)
    # 输出提示信息
    print(f"\n歌手: {artist.strip()}")
    print("歌名首字母: ", end="")
    for word in song_name.strip().split():
        print(word[0], end=" ")
    print()

    target = song_name.strip().lower()
    guesses = 0
    is_correct = False

    # 猜测循环
    while guesses < 2:
        guess = input("输入你的猜测:").strip().lower()
        if guess == target:
            if guesses == 0:
                score += 3
                print("答对了！加3分")
            else:
                score += 1
                print("答对了！加1分")
            is_correct = True
            break
        else:
            guesses += 1
            if guesses < 2:
                print("猜错了，再试一次")
    
    # 两次机会用完则结束游戏
    if not is_correct:
        print("两次机会都用完了，游戏结束")
        start = False

print(f"\n最终得分: {score}")

关键修改点 #

1. 移除答错分支的start = False，仅在两次机会用完且未答对时终止游戏
2. 统一将歌名和猜测转为小写，避免大小写匹配错误
3. 提前读取所有歌曲数据到内存，减少重复文件读取的开销
4. 优化代码结构，简化嵌套逻辑

二、文件数据层级化排序展示 #

假设music文件每行格式为歌曲名,歌手名，以下代码实现按歌手分组、字母排序的层级化展示：

def display_hierarchical_songs():
    song_data = {}
    # 读取并解析文件
    with open("music", "r", encoding="utf-8") as f:
        for line in f.read().splitlines():
            if not line.strip():
                continue
            song_name, artist = line.rsplit(",", 1)
            song_name = song_name.strip()
            artist = artist.strip()
            # 按歌手分组
            if artist not in song_data:
                song_data[artist] = []
            song_data[artist].append(song_name)
    
    # 按歌手名字母排序
    sorted_artists = sorted(song_data.keys())
    print("层级化歌曲列表:\n")
    for artist in sorted_artists:
        print(f"📀 {artist}")
        # 按歌曲名字母排序
        sorted_songs = sorted(song_data[artist])
        for idx, song in enumerate(sorted_songs, 1):
            print(f"  {idx}. {song}")
        print()

# 调用展示函数
display_hierarchical_songs()

功能说明 #

1. 读取文件并将歌曲按歌手分组存储
2. 对歌手名按字母顺序排序
3. 每个歌手下的歌曲也按字母顺序排序后展示
4. 跳过空行，避免无效数据干扰
