Personally I think the code has a very weird "smell"... Assuming you don't
have any way of rewriting the calling code and are stuck with editing this
single method, I'd suggest something along the lines of:
@staticmethod
def in_circle_check(obj_type, item, uuid):
if obj_type not in ['trees', 'flowers']:
return None
# trim the trailing 's', so this can be used elsewhere...
obj_type = obj_type[:-1]
if not (plant := get_plant_with_circles(uuid)):
return None
if plant[f'in_all_{obj_type}_types']:
return True
circle_objects = plant[f'{obj_type}_circle']['items']
if isinstance(circle_objects, list):
if not isinstance(item, (list, tuple)):
items = item
else:
items = [item]
if all([i in circle_objects for i in items]):
return True
return -1
