如何从filename中提取艺人名称和歌曲名称？

import re

def extract_artist_and_song(filename):
    # 根据文件名中的分隔符进行分割
    separator = " - "  # 假设分隔符为 " - "
    parts = filename.split(separator)
    
    if len(parts) >= 2:
        artist = parts[0].strip()  # 提取艺人名称
        song = parts[1].strip()  # 提取歌曲名称
        
        # 去除艺人名称和歌曲名称中的其他信息
        artist = re.sub(r'\([^)]*\)', '', artist)
        song = re.sub(r'\([^)]*\)', '', song)
        
        return artist, song
    else:
        return None, None

# 示例用法
filename = "Taylor Swift - Love Story.mp3"
artist, song = extract_artist_and_song(filename)
print("艺人名称:", artist)
print("歌曲名称:", song)

艺人名称: Taylor Swift
歌曲名称: Love Story
