What is missing in Python script

While using import yt_dlp, how do I modify this code

ydl_opts = {
    'outtmpl': save_path + '/%(title)s.%(ext)s',
    'postprocessors': [{
        'key': 'FFmpegExtractAudio',
        'preferredcodec': 'mp3',
        'preferredquality': '0',
    }],
}

to retrieve both artists and album information along with title for a complete profile of downloaded song?
