Loop-help for a newbie?

[pcsailor]

Hello,
I'm new here and this is my first post. I am aggressively learning Python and very excited to be doing so. Last year I took a 5-month MEAN stack boot camp (PrimeAcademy.io) and realized, despite my 20-year marine engineering career, I am not a natural coder. I'm struggling to 'think like a programmer' and I suspect it might be my system-based former career.
But that's another discussion so here's my question.

I'm building a spreadsheet using Openpyxl and I need some advice on how to loop the code. I'm not going to include all the code here because that seems obnoxious for a first post, but I'll include a snippet that's repetitive. I'm just having trouble how to conceptuale writing the code in a forLoop or While loop.

Thanks for the time.
I'm looking forward to alot of time in this forum.
BTW, what's the best way to get this forum on my Android phone? Tapatalk or another way?
Thanks,
