My goal is to create and fill data like (Field 3) from (Field 1) using the Field Calculator.
I was able to assigning sequential numbers using ArcPy code out there, but it gave me results of (Field 2).
I assume I need double loop to achieve the result of (Field 3), but the problem is I'm not familiar with ArcPy at all.
It would be great if you help me out with ArcPy or even point the sample code I can look at.
|Field 1||Field 2||Field 3|
