I'm looking for help tweaking the python code discussed here: Attribute Table Subtract Value From Previous Value
I'm having trouble figuring out how to adjust it for a date field in which I want to subtract a time by the previous time to get gaps. Here is what I have so far and the error received:
import arcpy from arcpy import da vertices ="CBR05_T2_10_1_2014_WLanduse_1" gap1=0 with arcpy.da.UpdateCursor(vertices, ["INDEX_", "Time", "GapDiff"]) as cursor: for row in cursor: gap2 = row row = datetime(gap2 - gap1) gap1 = gap2 cursor.updateRow(row)
Runtime error Traceback (most recent call last): File "", line 8, in TypeError: unsupported operand type(s) for -: 'datetime.datetime' and 'int'
