Is there any way how to set attribute rule using python expression instead of Arcade???

Thanks

Well yes and no.

You can use a python script to use an Arcade expression. See the example here

Is that actually used to fire a rule or just add one?

both... python is the delivery... attribute rule is the package 😁 Like Amazon (python home range)

Ok. I meant more like writing the script expression of the rule in python because it is quite complicated and currently uses some python libraries but I guess i have to learn that arcade now..

I don't think arcade imports python libraries

Hi @kirken ,

To confirm Dan's suspicion, Attribute Rules will only work with Arcade expressions. You cannot create an attribute rule using Python as the expression. The link shared by @DanPatterson before uses Python to configure the Attribute Rule, but inside it is still using the Arcade expression defined as a string inside the Python script.

In short, if you want to use Attribute Rules you will always need Arcade...

@XanderBakker looking for a way to use Attribute Rules to refresh lat/long fields after a point is moved. Right now we must do this manually with Calculate Geometry tool, and I am seeing it is possible to do it with Python, but I can't use Python to calc an Attribute Rule. I also can't use Arcade to translate into lat/long unless it is in Web Mercator... (we are using State Plane).... thoughts anyone?
