I have a lines shapefile. I made a small code to select some of its elements and turn them into a standalone layer. The code is like this:
arcpy.env.workspace = r"C:\MyDirectory\Mygdb.gdb" network = r"Linesshapefile" arcpy.MakeFeatureLayer_management(network,'Winners_lyr', "OBJECTID_12" in Winners) arcpy.SavetoLayerFile_management('Winners_lyr','Winners_lyr')
The last line is because, according to the documentation, the layer is not saved but only locally created, since I want to be able to access it also after the code.
Winners is an list containing integer numbers, like this:
Winners = [1, 4, 59, 330]
ObjectID_12is the code that univocally identifies my elements ( I think it received the appendix
_12 because this code is the result of several geoprecessing actions, including intersections)
when I run my code, anyway, I get this error:
File "C:\Program Files (x86)\ArcGIS\Desktop10.4\ArcPy\arcpy\management.py", line 6477, in MakeFeatureLayer raise e arcgisscripting.ExecuteError: ERROR 000358: Invalid expression 0 Failed to execute (MakeFeatureLayer).
I guess the issue is the SQL condition I wrote, but I am not sure how to fix it since the MakeFeatureLayer_management is not very generous of information concerning how to use this function. How can I solve the problem?
