Turn Layers off In ArcGIS Pro using Arcpy

Business_IntelligenceSoftware — Sat, 11 Dec 2021 13:39:28 GMT

I have a python script that should turn off all layers in a ArcGIS Pro project. But when I run it, the following error pops up:

File "<string>", line 2, in <module>
IndexError: list index out of range

Here is the python code I am using.

p = arcpy.mp.ArcGISProject("Current")
m = p.listMaps("Name of map")[0]
lyrList = m.listLayers()
for lyr in lyrList:   
   lyr.visible = False

Anyone know what I am doing wrong or missing?

The simplest answer would be that the map "Name of map" doesn't exist in your project. I don't think you have to specify a map name, or you can use wildcards, if you don't always know the name.

Thanks, using the wildcard worked. However, I didn't realize it would turn off the basemap also. Do you think I could fix that using an if/else statement?

You should be able to use the isBasemapLayer method - Layer—ArcPy | ArcGIS Desktop
