Okay, I'll fess up, this change request relates to sloppy coding in the original submission.
The original coding intent was to set up a set of consistent variable names for use in a function call.
In one of those phone-dog-kid distractions, the edit was not fully completed.
The editor did not throw a "variable defined but not used" warning (of course not, no compile, and linting not triggered, and cpep8 not set to catch these).
Execution testing was fine as old variable still had valid data.
The issue was noticed later when eyeballing the code for other reasons.
OCD kicks in and change has to be made.
As a code reviewer, having dealt countlessly with "what: Change why: per John" submissions, I thought my explanation was savvy.
So now do I get to say, whot? the code is self-documenting, can't you read it? ;-)
Okay, I understand exactly your point from having suffered much as a reviewer myself.
Time to fess up on the sloppy explanation.
Thanks for your patience. My apologies.
