I have a feature class of polylines that are duplicate, one on top of the other and i would like to delete all except for 1 and it doesn't matter witch one just as long as there is one left. I would like this to be done in arcmap. I have the following that identifies the duplicates but i am not sure  on how to delete duplicates in the set. import itertools, arcpy arcpy.env.overwriteOutput = True mxd = arcpy.mapping.MapDocument("CURRENT") df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0] lyr = arcpy.mapping.ListLayers(mxd, "Parcel_Lines1")[0] dsc = arcpy.Describe(lyr) sr = dsc.spatialReference oid_field_name = dsc.oidFieldName # get a cursor on the input features rows1 = arcpy.SearchCursor(lyr) # exclude features already compared once exclude = [] # iterate through the first coursor for row1 in rows1: oid1 = row1.getValue(oid_field_name) shp1 = row1.shape # get a second cursor on the same input features rows2 = arcpy.SearchCursor(lyr) # add the feature to be compared to exclude list exclude.append(oid1) # create a set to hold duplicate features group = set() # iterate through the second cursor for row2 in rows2: oid2 = row2.getValue(oid_field_name) shp2 = row2.shape # ignore features already compared if oid2 in exclude: continue # test equality if shp1.equals(shp2): # add both feature ids to the set of identical features group.add(oid1) group.add(oid2) # add the feature just compared to the exclude list exclude.append(oid2) if group: # if the group is not empty print group ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ ...
