ArcGIS Pro Calculator tool

[KateEkhator74]

Hello,

Am trying to use  the calculate field tool in ArcGIS pro and I am not familiar with the python 3 if then statements and how to use the code block. Please can anyone help with some tips on how to  do this.

Thanks.

You could use if, elif, else statements. e.g.

Expression:
Reclass(!WELL_YIELD!)

Code Block:
def Reclass(WellYield):
    if (WellYield >= 0 and WellYield <= 10):
        return 1
    elif (WellYield > 10 and WellYield <= 20):
        return 2
    elif (WellYield > 20 and WellYield <= 30):
        return 3
    elif (WellYield > 30):
        return 4

You might also consider trying Arcade. Arcade translates across to the ArcGIS Online environment, popup expressions, etc., and is worth learning.
