修复Python歌手统计代码在IDLE中的运行错误

核心错误 #

最后一行函数调用时参数拼写错误：print(favoriteSinger(n,song))里的song应该是songs，这会触发NameError，因为不存在名为song的变量。

另外，函数参数n在当前逻辑中没有被使用，属于冗余参数，可根据需求选择移除或添加输入校验（比如确保输入的歌曲列表长度等于n）。

修复后的代码 #

保留n参数的版本（仅修正拼写错误）

def favoriteSinger(n, songs):
    singer_counts = {}
    max_count = 0
    for singer in songs:
        singer_counts[singer] = singer_counts.get(singer, 0) + 1
        max_count = max(max_count, singer_counts[singer])

    favorite_singers = 0
    for singer, count in singer_counts.items():
        if count == max_count:
            favorite_singers += 1

    return favorite_singers

n = int(input())
songs = list(map(int, input().split()))

print(favoriteSinger(n, songs))  # 修正拼写错误：song → songs

移除冗余n参数的版本

def favoriteSinger(songs):
    singer_counts = {}
    max_count = 0
    for singer in songs:
        singer_counts[singer] = singer_counts.get(singer, 0) + 1
        max_count = max(max_count, singer_counts[singer])

    favorite_singers = 0
    for singer, count in singer_counts.items():
        if count == max_count:
            favorite_singers += 1

    return favorite_singers

n = int(input())
songs = list(map(int, input().split()))

# 可选：添加输入长度校验
if len(songs) != n:
    print("输入的歌曲数量与指定数量不匹配")
else:
    print(favoriteSinger(songs))
