split-string | Split a string on a given character or characters | Regex library

I am splitting a string into words for any uppercase letter and I am using the following regex:

I have this list where I want to only get the first word (I would like to remove the "engineering" in all of them) and I am displaying this in my html template like this:

So, I've got some python code

I am trying to split a string into several variables to eventually send each one as an instruction for one of six stepper motors. A string will be in a format like so:

D2 R' D' F2 B D R2 D2 R' F2 D' F2 U' B2 L2 U2 D R2 U

The issue is the steps within the string (e.g. D2 or R' or B) are all varying in length, so using step as a fixed length provides issues when recalling the individual sections (the varying lengths means that sometimes I will get part of one solution or a blank space then a letter). Also using something like unpacking doesn't work as the amount of steps in the string varies. So, how can I cut up a string like the one shown below, so I can assign each step to a individual variable?

From looking at a previous question (Python - split string into smaller chunks and assign a variable) I have realised I can do something along these lines:

I have a string that can look something like this:

I found a solution to cut a string like s = '247451517328' here: Split string every nth character? using using more_itertools sliced. But how can I apply this to a dataframe elegantly? e. g. a dataframe df

I am trying to create a regular expression that will allow me to split the strings below on the central comma only.

I am trying to split R15.49 to (R, 15.49) or

ZAR15.49 to (ZAR, 15.49)

I have tried one of the solutions here and implememted the function below:

I found interesting way to split string using tr or IFS
