group layer not iterable

mikeharol — Sun, 12 Dec 2021 09:09:49 GMT

for layer in m.listLayers():
    if layer.isGroupLayer and layer.name == "AerialLayers":
        for subLayer in layer:

I use to be able to iterate the groupLayer with arcpy.mapping but now with arpy.mp i get the following error:
TypeError: 'Layer' object is not iterable

Any insights appreciated.

Thanks

Mike

Turns out you have to call listLayers() on the grouplayer. Wasn't clear to me in the documentation i read.

for layer in ma.listLayers():
    if layer.isGroupLayer and layer.name == "AerialLayers":
        for subLayer in layer.listLayers():
            print(subLayer)

Hi Mike, glad to hear that listLayers() is working for you. Also, a good place for ArcPy questions is the Python group here: https://community.esri.com/community/developers/gis-developers/python
