Check whether a group layer is empty or not

[RanaMahmoud]

Hello,

I have an mxd file with around 100 layers and group layers. I'm trying to loop through all group layers and find out if they're empty or not (contains Feature class(es) or not). If a group layer is empty, I want to remove that group layer from the map.

I found the script to remove the group layer, but I couldn't figure out how to check if the group layer is empty or not

Anyone can help?
Thank you

Hi Rana,

You can use this code to remove empty group layers:

# Remove empty group layers
ListLyr = arcpy.mapping.ListLayers(df)
if ListLyr:
    for lyr in ListLyr:
        count = 0
        if lyr.isGroupLayer:
            for sublyr in lyr:
                count = count + 1

            if count == 0:
                arcpy.mapping.RemoveLayer(df, lyr)
                arcpy.AddMessage("Removed layer " + lyr.name)

mxd.save()

Thank you Geraldine, looks like it's gonna work. I'll test it as soon as I go back to work after the week-end

Thank you Geraldine, it works 🙂
Is there any way to loop through all levels of the group layers?
