Multivalue parameter and multi features

CCWeedcontrol — Wed, 06 Oct 2021 14:15:52 GMT

I have a script that I am trying to add/ include multiple parameters for multiple features. Parcels can have multiple case numbers associated with them. For example Parcel Pin12345 can have permit MC2021-0001 and CD20201-0001. I want to be able to create two separate parcels\features with the same Pin12345 but different permit numbers but only if I input multiple Parameters. If I just enter one parameter in then I just need one pin with the case I enter. Sometimes case number can have 2 or 10 parcels for that particular case. I am not sure what is the best way to do this but this is what I have and it works great with just one case no.

I have this but how do I split the GetParameter into two if two parameters(GetParameterAsText(2)) are given and apply one to each Pin?

lyr = arcpy.mapping.ListLayers(mxd, "TAXLOTS")[0] #Parcel numbers values = arcpy.GetParameterAsText(0) fieldName = "PIN" values = values.split(";") # split values into list values = ["'{0}'".format(v) for v in values] # add single quotes whereClause = "{0} IN ({1})".format(fieldName, ",".join(values)) arcpy.SelectLayerByAttribute_management(lyr, "NEW_SELECTION", whereClause) #selects the parcel numbers and creates Subject property if int(arcpy.GetCount_management("TAXLOTS").getOutput(0)) > 0: arcpy.Select_analysis("TAXLOTS", "SUBJECT") arcpy.SelectLayerByAttribute_management("TAXLOTS", "CLEAR_SELECTION") #AddsPermitNumber Casenum = arcpy.GetParameterAsText(2) SP = "SUBJECT" arcpy.SelectLayerByLocation_management(SP, "INTERSECT", SP, "", "NEW_SELECTION") if int(arcpy.GetCount_management("TAXLOTS").getOutput(0)) > 0: arcpy.CalculateField_management(SP, "PermitNo", '"' +Casenum+'"', "PYTHON_9.3") #"!{0}!".format(values) args = [arcpy.GetParameterAsText(1)for i in range(arcpy.GetArgumentCount())] #pCount = arcpy.GetArgumentCount(1) if args == 2: # dsc = arcpy.Describe(SP) fields = dsc.fields #out_fields = [dsc.OIDFieldName] fieldnames = [field.name for field in fields] #lstFields = [field.name for field in fields] with arcpy.da.SearchCursor(SP,fieldnames) as sCur: with arcpy.da.InsertCursor(SP,fieldnames) as iCur: for row in sCur: iCur.insertRow(row) else: pass

I get the following

Pin	Permit No
12345	MC2021-0002;CD2021-0005
12346	MC2021-0002;CD2021-0005

But need

Pin	Permit No
12345	MC2021-0002
12346	CD2021-0005

I currently coping and pasting features and I haven't been able to find any examples or ideas o how I can accomplish this so any help would be very appreciated.

Hopefully this helps someone, not sure if this is the best way but was the only thing I can find.

Code below line 8 is by JoshuaBixby.

Casenum = arcpy.GetParameterAsText(1) Splt = str(Casenum.split(";")) arcpy.AddMessage("Case ={0}".format(Splt)) SP = "SUBJECT" arcpy.SelectLayerByLocation_management(SP, "INTERSECT", SP, "", "NEW_SELECTION") if int(arcpy.GetCount_management("TAXLOTS").getOutput(0)) > 0: arcpy.CalculateField_management(SP, "PermitNo", '"' + Casenum +'"', "PYTHON_9.3") split_fld = "PermitNo" # Field to split split_delim = ";"# Delimeter for splitting field sys_flds = [ 'OIDFieldName', 'globalIDFieldName', 'ShapeFieldName', 'areaFieldName', 'lengthFieldName' ] desc = arcpy.Describe(SP) sys_fld_names = [ name for name in (getattr(desc, fld, '') for fld in sys_flds) if name ] usr_fld_names = [ fld.name for fld in desc.fields if fld.name not in [split_fld] + sys_fld_names ] cur_flds = ["SHAPE@", split_fld] + usr_fld_names with arcpy.da.Editor(desc.path) as edit: with arcpy.da.UpdateCursor(SP, cur_flds) as ucur: with arcpy.da.InsertCursor(SP, cur_flds) as icur: for row in ucur: shape = row.pop(0) split = row.pop(0).split(split_delim) for i in split[1:]: icur.insertRow([shape, i] + row) ucur.updateRow([shape, split[0]] + row)
