I took a long way round - going to go back and have a look at some of the pure regex solutions like @clmc9601
Spoiler
Part 1- just a simple regex to parse this out. First regex finds the multiplier and the second breaks it into X and Y
Part 2 - I couldn't get this working in regex alone - so I did something different:
- add don't()do() at the beginning
- Split the string by don't() - this means that every string is excluded until you see a Do
- Then split by do()
- Discard the first split before the first do and the rest are useful strings (anything before the first Do is covered by a Don;t
- then apply part 1
And here is the python for today - quite a few fun list bits - I may go back and use an accumulator just for kicks.
