I have a model (ModelBuilder) and within I added a python script to calculate a field. My problem now is, that I don't know how to make the output appear in my model as it is the same as the input (only with the field calculated).
I imagine there is a very simple way, but I am new to ModelBuilder and python and just can't think of it?
Alternatively, I could also try using the field calculator, but I would prefer it this way.
And here is my script:
import arcpy from arcpy import env env.workspace = arcpy.GetParametersAsText(0) # the workspace inLayer = arcpy.GetParameterAsText(1) # The shapefile inField = arcpy.GetParameterAsText(2) # The column in attr table with Area outField = arcpy.GetParameterAsText(3) # The column in attr table which should be calculated # Create a list from area field and find min & max value listing =  rows = arcpy.SearchCursor(inLayer) for row in rows: listing.append(row.getValue(inField)) del rows listing.sort() min = listing max = listing[-1] # Calculate the normalized value rows2 = arcpy.UpdateCursor(inLayer) for row2 in rows2: row2.setValue(outField, (max - row2.getValue(inField))/(max - min)) rows2.updateRow(row2) del rows2
