If you want to make it a little more robust, but slightly more complex you could use: "{0}-{1}".format("{0}".format(int(!ACONTROL!)).zfill(4),"{0}".format(int(!ASECTION!)).zfill(2)) This will yield: as the first suggestion will yield: ... View more

This code seems to get the result (assuming that I understand it now): import arcpy, os import sys import traceback from arcpy import env # Set environment settings # env.workspace = r"C:\GIS\Track1\1_Orig\int2" env.workspace = r"C:\Forum\updateCursorsAtts\testdata" # Set local variables dct_flds = {'PorousMed': ['PM1','PM2','PM3','PM4','PM5'],             'Kcond_1': ['Kcond1','Kcond2','Kcond3','Kcond4','Kcond5'],             'Porosity_1': ['Poros1','Poros2','Poros3','Poros4','Poros5'],             'Leng_m': ['leng_m1','leng_m2','leng_m3','leng_m4','leng_m5']} # changed fieldnames corresponding to the data # PorousMed: Text # K_1= Kcond_1: Double # Pity_1=Porosity_1: Double # Leng_m: Double def_tuple = ("",0,0,0) # create list of fields from dictionary (contains all fields: input and output) flds = [] for k, lst in dct_flds.items():     flds.append(k)     for fld in lst:         flds.append(fld) flds_in = dct_flds.keys() try:     fcList = arcpy.ListFeatureClasses("","POLYLINE")     print fcList     for fc in fcList:         print fc         # create the list from the input fields         valueList = []         with arcpy.da.SearchCursor(fc, flds_in) as curs:             for row in curs:                 valueList.append(list(row))         # correct for less than 5 elements         while len(valueList) <= 5:             valueList.append(def_tuple)         with arcpy.da.UpdateCursor(fc, flds) as curs:             for row in curs:                 for fld_in, lst_out in dct_flds.items():                     # val_in = row[flds.index(fld_in)]                     for fld_out in lst_out:                         num = int(fld_out[-1:])                         lst_vals = list(valueList[num])                         row[flds.index(fld_out)] = lst_vals[flds_in.index(fld_in)]                 curs.updateRow(row) except Exception as e:     print e     tb = sys.exc_info()[2]     tbinfo = traceback.format_tb(tb)[0]     pymsg = "PYTHON ERRORS:\nTraceback info:\n" + tbinfo + "\nError Info:\n" + str(sys.exc_info()[1])     msgs = "ArcPy ERRORS:\n" + arcpy.GetMessages(2) + "\n"     print pymsg + "\n"     print msgs I'll attach the updated dataset for you to check the result.
