Update_look with filters in Python

I am trying to use the update_look command in order to update the filter of a saved look with a new list of IDs. Is there an example of what the correct way to enter my filter name and content into the update_look request?
I have been referring to this page but I could use a little help on what to put in the “filter” spot in the JSON in order to make the filter update how I want.
