Check if specific group(s) are in context - Pyson

Hello, Is there a reason why you cannot just remove write access for this field on this group ?

See:

Allow user to view and save a field, but not edit

On the invoice form, suppose I don’t want a user to be able to change the field ‘Invoice Address’, which is populated automatically when the Party is selected. To do that I disable write access for the field, but now, on saving the record, that field is not saved. How can I allow the field to be viewed and saved, but not edited by a specific user?
