Ok so there's no easy way to title this to get the information I really want to get at. But I feel like the longer winded explanation is fairly simple.

So I'm in a programming for data science class (so extremely new to programming, very base level) and working with my own dataset for an injury study using force plates. Data is already broken down and shows combined, left foot, right foot to come up with a variety of different categories (for example theres a "left peak breaking force", "right peak breaking force" and a "L/R average breaking force".

One big problem. The data has to be converted from Left, and Right to "injured" and "uninjured" sides to get at what we want from the project.

Is there any clean/not completely messed up way to do this through code to go through and split up L and R sided injuries, then reflect that in the values in the heading?
