I'm trying to iterate through a feature class and select each feature one by one by using the OBJECTID field. When I use a single value, the SelectLayerByAttribute works, but how do I compare the OBJEECTID to a variable that increases in count through the loop. The program is then suppose to create a layer for each feature in the feature class. This is what I have so far:
import arcpyimport osarcpy.env.workspace = "C:\Users\Daimon Nurse\Desktop\DFMPROJECT\DFMPROJECT.gdb"arcpy.env.overwriteOutput=Trueinlayer = "C:\Users\Daimon Nurse\Desktop\DFMPROJECT\DFMPROJECT.gdb\ZonesPolyline"with arcpy.da.SearchCursor(inlayer, ("OID@", "SHAPE@AREA")) as cursor: i = 1 for row in cursor: print("Feature {0} has an area of {1}".format(row[0], row[1])) outlayer = "ZonePolygon" arcpy.MakeFeatureLayer_management (inlayer, outlayer) arcpy.SelectLayerByAttribute_management (outlayer, "NEW_SELECTION", """ "OBJECTID" = 1 """) output = r'C:\Users\Daimon Nurse\Desktop\Grounds Project\DFMGROUNDS.gdb' outfile = os.path.join (output, i) arcpy.CopyFeatures_management(outlayer, outfile) print i i = i + 1
