I know you can use an iterator in model builderModelBuilder, 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, fields(multivalue,obtained from input), and workspace. This script will split the shapefile into multiple shapefiles based on the fields you select, and output them into a folder of your choice.
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)
