I would like to automate the process of making some certain feature layers.
I made a list of lists that goes like that: [[feature class, subtype],[feature class,subtype],...]
I'd like to loop through the list and make feature layers using the items in the smaller lists for output paths and queries. So far I wasn't able to retrieve them correctly.
bigNeighborList=[["ExtractA",0],["ExtractA",1], ["BuiltupA",0],["CoastA",3],["SwampA",0],["WatrcrsA",0],["WatrcrsA",1],["LakeresA",0]] #["LakeresA",2],["LakeresA",1],["WatrcrsA",2],["GroundA",0],["Landfrm1A",1],["CropA",1],["CropA",2],["GrassA",0],["TreesA",1],["TreesA",0], ["FirebrkA",0],["SwampA",1],["SwampA",2],["CropA",3]]
for itemA in bigNeighborList:
bigFC = [itemA[0] for itemA in bigNeighborList] #retrieve the first item - feature class name from a smaller list
subtype = [itemA[1] for itemA in bigNeighborList] #retrieve the second item - subtype number
outputItemA = os.path.join(wrksp100, str(bigFC[0]))
print(outputItemA)
qry = "%s = %d " % (subField,int(subtype[0])) ##query to choose the right subtype
tempLyr = arcpy.MakeFeatureLayer_management(outputItemA,str(bigFC)+"_lyr",qry) #temporary layer for every list item
The print statement returns the path C:\DAR...3\ExtractA
8 times for every itemA
in the list and creates new ExtractA tempLyr
, though named with all first items from small lists "['ExtractA', 'ExtractA', 'BuiltupA', 'CoastA', 'SwampA', 'WatrcrsA', 'WatrcrsA', 'LakeresA']_lyr"
over and over.
Something wrong with indexing?
