I know you can use an iterator in model builder, but if you prefer to use python here is something I came up with. Add the script to a toolbox with the parameters in order as Input shpfile, feilds(multivalue,obtained from input), and workspace. This script will split the shapefile into multiple shapefiles based on the feilds you select, and output them into a folder of your choice. Hope this helps. (This is the first time Ive posted a script. Please vote up if it helps you at all. Thanks a ton.)
import arcpy, re
arcpy.env.overwriteOutput = True
Input = arcpy.GetParameterAsText(0)
Flds = "%s" % (arcpy.GetParameterAsText(1))
OutWorkspace = arcpy.GetParameterAsText(2)
myre = re.compile(";")
FldsSplit = myre.split(Flds)
sort = "%s A" % (FldsSplit[0])
rows = arcpy.SearchCursor(Input, "", "", Flds, sort)
for row in rows:
var = []
for r in range(len(FldsSplit)):
var.append(row.getValue(FldsSplit[r]))
Query = ''
Name = ''
for x in range(len(var)):
if x == 0:
fildz = FldsSplit[x]
Name = var[x] + "_"
Query += (""" "%s" = '%s'""" % (fildz, var[x]))
if x > 0:
fildz = FldsSplit[x]
Name += var[x] + "_"
Query += (""" AND "%s" = '%s' """ % (fildz, var[x]))
OutputShp = OutWorkspace + r"\%s.shp" % (Name)
arcpy.Select_analysis(Input, OutputShp, Query)
