My Question or Issue

I am trying to write a python script that just scrapes other users' playlists and adds songs in them to my own playlist. When running the following script:

import spotipy
from spotipy.oauth2 import SpotifyClientCredentials

# Set your Spotify API credentials
client_id = "my_client_id"
client_secret = "my_client_secret"
scopes = ["user-playlist-create", "user-playlist-modify"]

# Authenticate with the Spotify API
client_credentials_manager = SpotifyClientCredentials(client_id=client_id, client_secret=client_secret)
sp = spotipy.Spotify(client_credentials_manager=client_credentials_manager)

# Define the name and description of your playlist
playlist_name = "new_playlist"
playlist_description = "a new playlist built from other users' playlists"

# Create the playlist on your Spotify account
playlist = sp.user_playlist_create(user="spiritkhakis", name=playlist_name, description=playlist_description)
playlist_id = playlist["id"]


# Add songs from other users' playlists to your playlist
songs = []
for user in ["user1", "user2", "user3"]:
    playlists = sp.user_playlists(user=user)
    for playlist in playlists["items"]:
        if playlist["name"] == "Your Top Songs 2022":
            playlist_tracks = sp.playlist_tracks(playlist_id=playlist["id"])
            for track in playlist_tracks["items"]:
                songs.append(track["track"]["id"])

# Add the songs to your playlist
sp.user_playlist_add_tracks(user="spiritkhakis", playlist_id=playlist_id, tracks=songs)

# Print a message to confirm that the playlist has been created
print(f"Successfully created playlist: {playlist_name}")


# Print a message to confirm that the playlist has been created
print(f"Successfully created playlist: {playlist_name}")

 I receive the following error message:

Couldn't read cache at: .cache
Couldn't write token to cache at: .cache

During handling of the above exception, another exception occurred:

    raise SpotifyException(
spotipy.exceptions.SpotifyException: http status: 403, code:-1 - https://api.spotify.com/v1/users/spiritkhakis/playlists:
 This request requires user authentication., reason: None

Not sure what is causing this, since I'm pretty sure I have authenticated the user in question (spiritkhakis is my own account, and the account with which I have registered the app). I saw one forum post saying I needed to navigate specifically to an "Authenticate a New User" option under the "Dashboard" tab on the Spotify Developer website, but when I navigate to my dashboard, there is no such option.

All help is appreciated. Thanks!

If you want to use user_playlist_create(), you can't use Client Credentials. You can read this at the bottom of the error message: "This request requires user authentication.". You can read here how to use User Authentication inside your script. You need to use the Scopes: playlist-read-private, playlist-read-collaborative, playlist-modify-private, playlist-modify-public.

At the top, there's an error message saying "Couldn't write token to cache at: .cache". Maybe it has something to do with the other message, or you are running your script from somewhere Python doesn't have read/write access.
