Now, all testing is done at the point where it is needed. There are no
running totals that could cause accounting errors, your final data
structure is an easy to use dict, unecessary tests have been eliminated,
loops have been de-nested visually and logically, and, most importantly,
the indentation level is kept manageable.
I think you will be able to see how this latter code evolved from yours.
I used to program just like you and it has taken me a few years to
develop these little rules for tightening my code.

That they wouldn't be seems an implementation bug and perhaps that bug

tightens up code in many cases, and seems that it would break
