I am trying to create a Python Node for deleting Filled Regions with a given name. I keep getting the error shown in the image.

an if statement requires ==
so your line should run like:

if region.Name == name:

Hi @Ben_Veasey ,
this might not be the only issue, but the exception reffers to this line :

	if region.Name() = name:

change it to :

	if region.Name() == name:

Ah, excellent responses. Thanks.

I am getting a new error shown in the image…

Name is a property not a method, so you don’t need the “()” .

Just replace :

	if region.Name() == name:

with :

	if region.Name == name:

about the accepted solution.
my reply was the exact solution.
maybe have a closer look at solutions :wink:

You are right…I would love to have ticked both as the Solution. Mostafa’s statement "Name is a property not a method, so you don’t need the “()” " was extremely helpful to me too…
