Hi,I am trying to display results that did not match from geocoding that displays Member IDs in a tkMessageBox. The code below seems to work (the last print statement shows the expected IDs), but the tkMessageBox only displays the last value in the valueList. Any advice on how to display all of the values in the valueList in the tkMessageBox would be greatly appreciated.Thanks,Bimport arcpy, tkMessageBox input_MEM = r"C:\test.gdb\Members" field = "MEM_ID" valueList = [] rows = arcpy.SearchCursor(input_MEM,"\"Loc_name\" IS NULL","",field,"") for row in rows: value = row.getValue(field) if value not in valueSet: valueList.append(value) for ID in valueList: print ID tkMessageBox.showinfo("Process Completed","Member(s) " + str(ID) + " could not be located.")
