I have a string value (football score) in my Pandas dataset. I would like to extract the home goals and the away goals from this score.

The score can be written in a couple of ways (sometimes it is won on penalties and presented with brackets.

Standard score:

"4-2" I would like to extract 4 as the home goals and 2 as the away goals.

Won on penalties:

"(5) 2-3 (4)" I would like to extract 2 as the home goals and 3 as the away goals and ignore the brackets

Is there a reg-ex (or 2) that would give me the 2 values I require in both instances. Maybe checking for the “-” and take the number either side of it?
