I am trying to add shapefile using ArcPy, but each time my script is ending in showing runtime error? I am using ArcGIS 10.

Here is my script

import arcpy
from arcpy import env

Master="G:\path\To\ShapeFile.shp"

mxd = arcpy.mapping.MapDocument("CURRENT")

df = arcpy.mapping.ListDataFrames(mxd,"*")[0]
layer = arcpy.mapping.Layer(Master)
arcpy.mapping.AddLayer(df, layer,"BOTTOM")

arcpy.RefreshActiveView()
arcpy.RefreshTOC()

This script works fine when I add .lyr files, but why it isn't working for .shp

  • What is your path to shapefile? Could it be something special in the path string? Try the same script with C:\GIS\Simple.shp to make sure it works with the simple path. – Alex Tereshenkov Mar 3 '16 at 9:37

    I assume you run the script in the ArcMap session? When I do with my shapefile, the code you've published works. – Alex Tereshenkov Mar 3 '16 at 9:38
  • I am running it in ArcMap's python window, therefore, yes in the ArcMap session. Mine is ArcGIS 10. What version you're using? @AlexTereshenkov – Mario Mar 3 '16 at 10:06

Try:

Master = r"G:\path\To\ShapeFile.lyr"

arcpy.mapping.Layer only works with .lyr files acccording to Esri documentation but it seems to accept .shp files as well.

See here for info about raw strings

  • I already tried this, it's also giving the same error. – Mario Mar 3 '16 at 9:22
  • The function only accepts .lyr files. – Nxaunxau Mar 3 '16 at 9:38
  • What to do for .shp files? – Mario Mar 3 '16 at 9:47
  • Sorry, that script should work with shapefiles....can you post the full error msg? – Nxaunxau Mar 3 '16 at 9:52
  • Question title itself shows the full error message, what I see on the ArcGIS python window. – Mario Mar 3 '16 at 9:54

Problem with your path, so check that.

Change to Master=r"G:\path\To\ShapeFile.shp"
