How do i get this code to return all the songs in the playlist using spotipy?

Question

I am trying to get the spotify audiofeatures from the songs in a playlist using spotipy. However, I only get the data of the last song in the playlist. My code looks like this:

import spotipy
from spotipy.oauth2 import SpotifyClientCredentials 
import time
import numpy as np
import pandas

client_id = 'ID'
client_secret = "Secret" 

#Authentication - without user
client_credentials_manager = SpotifyClientCredentials(client_id=client_id, 
client_secret=client_secret)
sp = spotipy.Spotify(client_credentials_manager = client_credentials_manager) 

playlist_link = "https://open.spotify.com/playlist/3VJlwgnV4IaxGK8uIEZMjV? 
si=ca8c506dd5d04663"
playlist_URI = playlist_link.split("/")[-1].split("?")[0]
track_uris = [x["track"]["uri"] for x in sp.playlist_tracks(playlist_URI)["items"]] 

for track in sp.playlist_tracks(playlist_URI)["items"]:
    #URI
    track_uri = track["track"]["uri"]

    #Track name
    track_name = track["track"]["name"]

    #Main Artist
    artist_uri = track["track"]["artists"][0]["uri"]
    artist_info = sp.artist(artist_uri)

    #Name, popularity, genre
    artist_name = track["track"]["artists"][0]["name"]
    artist_pop = artist_info["popularity"]
    artist_genres = artist_info["genres"]
 
    #Album
    album = track["track"]["album"]["name"]
 
    #Popularity of the track
    track_pop = track["track"]["popularity"]

    result = track_name,  sp.audio_features(track_uri)

    result

I have filled in the ID's but I removed them here for privacy.

Your question didn't give me the necessary information to run the code, so I have answered this blind.

You are not returning at the end of the for loop and you probably want to add the results to a structure and return that.

The below has (guessed) what you want. Few other comments:

• Capitalise your constants.
• Use functions.
• Try to avoid global scope entirely.
• Build a list and at the end of the for loop return it.
• Remove unused imports and variables.

import spotipy
from spotipy.oauth2 import SpotifyClientCredentials

CLIENT_ID = 'ID'
CLIENT_SECRET = "Secret"
PLAYLIST_LINK = "https://open.spotify.com/playlist/3VJlwgnV4IaxGK8uIEZMjV?si=ca8c506dd5d04663"

CLIENT_CREDENTIALS_MANAGER = SpotifyClientCredentials(
    client_id=CLIENT_ID, client_secret=CLIENT_SECRET
)
SP = spotipy.Spotify(client_credentials_manager=CLIENT_CREDENTIALS_MANAGER)


def get_playlist_uri(playlist_link):
    return playlist_link.split("/")[-1].split("?")[0]


def get_tracks():
    tracks = []
    playlist_uri = get_playlist_uri(PLAYLIST_LINK)
    for track in SP.playlist_tracks(playlist_uri)["items"]:
        track_uri = track["track"]["uri"]
        track_name = track["track"]["name"]
        result = track_name, SP.audio_features(track_uri)
        tracks.append(result)

    return tracks


the_stuff = get_tracks()

Edit

This popped up as a notification as someone thought it was helpful. Here is a more updated version of how I would do it.

from spotipy import Spotify
from spotipy.oauth2 import SpotifyClientCredentials


from typing import NamedTuple, List


class Track(NamedTuple):

    uri: str
    name: str
    features: List[str]

    @classmethod
    def from_spotify(cls, spotify: Spotify, track: Dict) -> 'Track':
        uri: str = track["track"]["uri"]
        return cls(
            uri=uri,
            name=track["track"]["name"],
            features=spotify.audio_features(uri)
        )


def get_playlist_uri(playlist_link: str):
    # this should use url_parse or something...
    return playlist_link.split("/")[-1].split("?")[0]


def get_tracks_from_playlist(client: Spotify, playlist_name: str) -> Iterable[Track]:
    for track in client.playlist_tracks(playlist_name)["items"]:
        yield Track.from_spotify(client, track)


if __name__ == "__main__":
    CLIENT_ID = 'ID'
    CLIENT_SECRET = "Secret"
    PLAYLIST_LINK = "https://open.spotify.com/playlist/3VJlwgnV4IaxGK8uIEZMjV?si=ca8c506dd5d04663"

    client = SpotifyClientCredentials(client_id=CLIENT_ID, client_secret=CLIENT_SECRET)
    spotify = Spotify(client_credentials_manager=client)

    playlist = get_playlist_uri(PLAYLIST_LINK)
    tracks = tuple(get_tracks_from_playlist(spotify, playlist))
