Spotify Playlist Manager

Overview

This Python script interacts with the Spotify API to manage playlists and fetch user information. It uses the Flask framework to run a local server and handle HTTP requests.

FAQ

• Does it work with albums? No.
• Does it delete or replace older randomized playlists? No.
• How long does it take? Around 2 minutes at max.

How it Works

1. The script first reads the configuration values from the config.yml file, which includes the Spotify access token and playlist ID.
2. It then starts a Flask server on port 8888.
3. When a user navigates to the server's URL in a web browser, the server responds with the index.html page.
4. The user can enter a playlist URL and choose whether to use the Liked Songs playlist.
5. When the user clicks the "Log In" button, the server sends a POST request to the Spotify API to add tracks to the specified playlist.
6. The server prints a success message if the tracks are added successfully, or an error message if there's a problem.

Optimizations

• The script uses the requests library's built-in JSON support to send the playlist data to the Spotify API, which simplifies the code and reduces the chance of errors.
• It also uses Flask's built-in support for serving static files, which makes it easy to serve the index.html page.

Problems

• The script doesn't validate the playlist URL entered by the user, so it could crash if the URL is not a valid Spotify playlist URL.
• It also doesn't handle errors that could occur when reading the config.yml file, such as the file not existing or not being in the correct format.
• The script does not delete old Randomized Playlists because for some reason the Spotify Web API did not give me updated playlists so I gave up.

How to Run

To run the script, use the following command:

py main.py
