I am writing some code with Python and Spotipy and I'm relatively new to coding. I have some code that get all the info about a Spotify playlist and prints it out for me:
from spotipy.oauth2 import SpotifyClientCredentials
import spotipy
import json
client_credentials_manager = SpotifyClientCredentials()
sp = spotipy.Spotify(client_credentials_manager=client_credentials_manager)
playlist_id = 'spotify:playlist:76CVeJDw2b90up5PgkZXyU'
results = sp.playlist(playlist_id)
#print(json.dumps(results, indent=4))
print((json.dumps(results, indent=4)))
It works well and gives me all the info. My problem is that I only need specifics from the print:

From this long print I somehow need to extract the Artist and the song title and preferably make it into a variable. Also not sure how this would work if there are multiple songs in a playlist.
It's also a solution if I can print out only the Artist and the title of the song without printing out all the information.
sp.playlist
returns a dictionary, so you can simply access its values by their keys. For example:
>>> results['name']
'TEST'
JSON is a data serialization format, ie a standardized way of representing objects as pure text and parsing them back from the text. json.dumps
therefore converts the dictionary object to a string of text. This is useful if you want to for example save the results to a file and load it back later. You don't need it to access contents from results
.
(This is a playlist though—you will need to get information on each song/track to get its artist and name.)
Based on your posted example it appears that you have only 1 song named "Africa" by artist "TOTO". Copying the track to have two songs, I added another track with two artists for testing the arrays.
If that json is loaded into a variable named results
then (as @xcmkz said) you have a python dictionary and can process accordingly.
Try working with the following to transverse through your dict appending artists and songs to lists:
song_dict = {}
for track in results['tracks']['items']:
song_name = track["track"]["name"]
a2 = []
for t1 in track['track']['artists']:
a2.append(t1['name'])
song_dict.update({song_name: a2})
print(f'Dictionary of Songs and Artists:')
for k, v in song_dict.items():
print(f'Song --> {k}, by --> {", ".join(v)}')
Results:
Dictionary of Songs and Artists:
Song --> Africa, by --> TOTO
Song --> Just Another Silly Song, by --> Artist 2, Artist 3
