Get albums for a specific artist

[xiaopeiwu]

Hi! Thank you for this great package. I've tried a few simple searches and am looking in the documentation, but I can't seem to find a method to get the albums for a specific artist based on the list of songs returned. I'm seeing that although the Artist object has a song attribute, the Song object doesn't have an album attribute. However when I dump the Song object into json I do see album info in there.

Is there a reason for this? Or am I simply missing something obvious? I'm trying to build a dataset for lyrics of an artist where album may be a good feature to have.

Many thanks!

Hi. To get an Artist's albums you can use the Genius.artist_albums method and then get more information from there:

albums = genius.artist_albums(45)['albums']
for album in albums:
    full_album = genius.search_album(album_id=album['id'], get_full_info=True)

As for why some attributes are present in the dict, but not in the object, it's because of consistency. Depending on the value of the get_full_info parameter there will be more or fewer data in the response, but LyricsGenius has to make sure that the values are consistent, so some of them have been removed from the object (but still available through to_dict if you want them). We'll probably change this in the future to provide all possible values.

Thanks for all your help! I did a bit more testing and it appears that there is a difference between using the genius.song method directly and using search_song or search_artist while setting get_full_info=True and then use to_dict(). However, this thread more than answered my original question so I will mark it as answered and maybe open an issue separately. Many thanks again!

As far as I can remember the only difference between genius.song and genius.search_song(get_full_info=True).to_dict is that the latter adds two values: artist which is the artist name and lyrics which contains the lyrics.

I've made a small test case to show the difference:

genius = lyricsgenius.Genius(timeout=20, sleep_time=5)  # getting access token from an environment variable
test_song = genius.song(1081664)
test_full_info = genius.search_song("Wonderwall", "Radiohead", get_full_info=True).to_dict()
print(len(test_song["song"]))
print(len(test_full_info))

These are the same song. test_full_info is missing quite a few values that are present in test_song. So I've used the debugger and it appears that in line 430 of genius.py, there is this condition:

        if song_id is None and get_full_info is True:
            new_info = self.song(song_id)['song']
            song_info.update(new_info)

And since the song does have a song_id, this condition evaluates to False, and so the update using genius.song to the public API call result never happened.

Package version is 3.0.0

That's been resolved in #181.

Oh I see! I should've checked out #181 like I said I would :)
