Calling a map using it name (Python)

AmitCohen — Wed, 16 Dec 2020 12:11:56 GMT

Hi,

I have a map name (strings).

I want to know how to access the listLayer() of a specific map by the "string" name of the map.

x = "Map1" for i in x.listLayers(): print("Layer: " + i.name)

not really working because I don't know how to "call" the specific map.

Thanks!

Maybe this example could help you:

https://pro.arcgis.com/de/pro-app/arcpy/mapping/layer-class.htm

import arcpy aprx = arcpy.mp.ArcGISProject(r"C:\Projects\YosemiteNP\Yosemite.aprx") m = aprx.listMaps("Yosemite National Park")[0] for lyr in m.listLayers(): if lyr.supports("DEFINITIONQUERY"): lyr.definitionQuery = "" if lyr.supports("SHOWLABELS"): lyr.showLabels = False aprx.save() del aprx

aprx = arcpy.mp.ArcGISProject(r"C:\Projects\YosemiteNP\Yosemite.aprx") m = aprx.listMaps("Yosemite National Park")[0]

from the code sample on the layer class page Layer—ArcGIS Pro | Documentation

import arcpy aprx = arcpy.mp.ArcGISProject(r"C:\myproject.aprx") my_map = aprx.listMaps("Your Map")[0] for lyr in my_map.listLayers(): print("Layer: " + lyr.name)
