is it possible to convert this AML into python? (arcedit)

Question

I'm trying to replicate this code (both delete) in python, my previous question is related to this arcpy 10.3.1 being used with proper license using coverage files display 0 arcedit &if [show program] ne ARCEDIT &then &do /*IF1 &type ERROR: The Arcedit module could not be invoked &setvar run_status := -1002 &return &end /*IF1 /*** Remove non-topological lines /* graphics off edit %path_poly_cover% editfeature line select line_type in {%valid_line_type_list%} nselect &if [show number select] gt 0 &then &do /*IF1 delete &end /*IF1 /*** Remove non-topological points /* editfeature point select pnt_type in {%valid_pnt_type_list%} nselect &if [show number select] gt 0 &then &do /*IF1 delete &end /*IF1 save removeedit %path_poly_cover% yes /*** Return to the arc module /* &if [show program] eq ARCEDIT &then &do /*IF1 removeedit all yes quit yes &end /*IF1‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

It could be a bug, since not many report issues with the Coverage tools anymore, so might never get written up. And if so, I doubt they will fix it, but might be worth putting a tech support request to ask.

But if not a bug, it's just a matter, in my opinion, of getting the right infoExpress syntax with quotes and all...and maybe so one step at a time, vs in a series as infoExpress is supposed to allow.  It would create more temp coverage perhaps, but if the main thing is to get it to work, temp coverages can always be deleted at the end of the script.

like you I'm not able to make the infoexpress work and I am able to a clean_arc call.

the reselect_arc would have been a nice alternative to my delete row issue.

I suggest taking a look at http://desktop.arcgis.com/en/arcmap/10.3/tools/coverage-toolbox/select.htm or ArcGIS Help 10.1 if pre-10.1, you'll need to do a quick web search for the help So, I can get you part way there. I haven't figured out the correct syntax for the reselect and nselect yet. The error I'm getting is Enter a logical expression. (Enter a blank line when finished) >: RESELECT FID LT 16 ** Item "FID" not found ** >: NSELECT NSELECT cannot be the first selection expression. Character string expected. ** An expression must start with RES, ASEL, NSEL or ITEMS. ** NO VALID EXPRESSION ENTERED ** *** UNABLE TO PERFORM ACTION *** Bailing out of EVALUATE Failed to execute (Reselect). Failed at Wed Sep 14 19:03:52 2016 (Elapsed Time: 0.37 seconds) I have also tried it with RES and NSEL. Here is the code that I have so far. Again, it gives some good info up to the infoExpress and the Reselect_arc part import arcpy inCover = r"C:\Workspace est\bl01" # inCover = r"c:\Data\cea01apr" # this assumes cea01apr is the Coverage name arcpy.env.workspace = inCover featureType = 'point' # this is the feature type recCountIn = int(arcpy.GetCount_management(featureType).getOutput(0)) print("Number of {0} records in {1}: {2}".format(featureType, inCover, recCountIn)) # these aren't used, but good info featureClassList = arcpy.ListFeatureClasses() fieldList = arcpy.ListFields(inCover, "", featureType) fieldString = [str(x.name) for x in fieldList] print(fieldString) tempCover = r"C:\Workspace est\cl01testIn" try: arcpy.Copy_management(inCover, tempCover) print(" Copy worked") except: print(" Copy didnt work, may already exist") tempCoverOut = r"C:\Workspace est\cl01Out" fidfilter= 'fid < 16' # just for the sake of showing 15 vs one record... # take a look at http://resources.arcgis.com/en/help/main/10.1/index.html#/Select/001300000005000000/ # or http://desktop.arcgis.com/en/arcmap/10.3/tools/coverage-toolbox/select.htm print(" Reselect {0} from {1} then nselect for the other {2} and save to new coverage".format(fidfilter, recCountIn, (recCountIn - int(fidfilter[-3:])))) infoExpress = ["RESELECT FID LT 16", "NSELECT"] print(" my test infoExpress: {0} but doesn't work".format(infoExpress)) """ # sample from help pages infoExpress = ["RESELECT stream_name CN 'AQUEDUCT'", "NSELECT", "RESELECT stream_order > 3", "ASELECT length > 10000"] """ # Execute Reselect arcpy.Reselect_arc(tempCover, tempCoverOut, infoExpress, featureType, "", "") ‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Unless you have to do it all in the source coverage, I would use a copy (just in case) and then do a Reselect to a new coverage. If you run it more than once, you will have to so clean up, of course. And that assumes you get it to work, which as mentioned, right now the infoExpress is not quite right yet. Also, change to your input/workstation, etc. As mentioned in the other thread, you might be better off moving to a FGDB and featureclasses now, but I was always a coverage fan, and know there may be reasons....so, work with what you need to. have fun!
