How to turn off headings from legend using python?

WesleyCosta

Well, I'm using ArcGIS Pro 2.7 and I want to turn off the 'Headings' from Legend Item. I know how to do it manually, but I need to make a script. Thanks by attention!

Hello Wesley,

This can be accomplished using Python CIM Access:

https://pro.arcgis.com/en/pro-app/latest/arcpy/mapping/python-cim-access.htm

Here is a snippet of code that does what you need.

p = arcpy.mp.ArcGISProject('current')
lyt = p.listLayouts()[0]
#Get the layout's CIM definition
lyt_cim = lyt.getDefinition('V2')

#Iterate though all layout elements to find the Legend element
for elm in lyt_cim.elements:
  if elm.name == "Legend":
    #Legend item changes
    for itm in elm.items:
      if itm.name == "GreatLakes":
        #Update visibility
          itm.showLayerName = True
          itm.showHeading = False   

#Set the CIM changes back to the layout
lyt.setDefinition(lyt_cim)

 

There are many Python CIM Access samples located here (including legenditem changes):
