Which Premier League match is most exciting to watch on a full match replay?

Living in Los Angeles now means that I'm unfortunately completely out of sync with Premier League football matches. The upside of this is that by the time I get up on the weekend most games have been played and I can watch full match replays on NBC Sports Live Extra. As a mostly neutral fan I'm interested in watching the most exciting games each weekend but there's no way to tell which game I should watch without knowing the final score and therefore spoiling the match (as far as I can tell).

Today I wrote a Python script that returns a list of the most recent round of Premier League games ordered by excitement and without any spoilers. I used the free API at football-data.org. It was my first experience with JSON data and the trickiest part was definitely trying to connect with a remote API for the first time and get the data in a usable dictionary format.

The ranking of the matches is calculated using the formula (total goals)/(difference in goals scored), where a higher number is better. For example, I'd rather watch a tight 2-1 (3/1 = 3) than a one-sided 5-1 (6/4 = 1.5) hiding. The script simply returns a list of matches without any goal information with the first being the most exciting.
