I know you are aware of devcontainers, so no need to explain that I guess :) I'm trying to keep my (work) laptop clean of most dependencies, so I just created this small devcontainer to prevent having to install Python! https://github.com/rvanmaanen/spotifyplus_token_generator

Describe the solution you'd like

Feel free to do with this whatever you want :D

Describe alternatives you've considered

Installing Python

Additional context

Unfortunately this can't run from codespaces as far as I know as the URL for the codespace is only accessible when logged in to GitHub so the callback from Spotify won't make it there.
