Episode 4: Playlist Plus

The Final Showdown.

Now that we've improved our genre based playlist generator. We expose a hint parameter allowing the user to suggest a better bonus movie. The bonus movie is chosen from the movie that has the most similar name to the hint.
This is achieved by importing a string edit distance package using Metaflow's conda based dependency management feature. Dependency management builds isolated and reproducible environments for individual steps.
