Hi, I am using ArcGis 10.2., I have a problem with an expression i have created in Python for field calculator. I want to process a column with distances in an attribute table. I want the value in the first row to be minus 10, and starting from that row to abstract each one with the next row.
My columns i want to be like that:
Should i click on State column to do my calculations?
Can't i put my column in a list, and treat it as it is?
In codeblock I can process something only by creating a def?
How complicated can that be??
I tried UpdateCursor, row.GetValue but i didn't manage to do it. I have read a lot of examples but none of them were very usefull for that occasion.
Thanks for your time
