Slice objects in sublists sharing a common propery

Some times you want to slice a list of objects (or dictionaries) in sub-lists of objects that share a common property. In those cases you can use this simple snipet:

def slice(objects, prop):
 """
 slice objects in sub-lists sharing a common property
 """
 if not objects:
 return []

 def get_prop(obj, prop):
 if not isinstance(objects[0], dict):
 return obj.__dict__[prop]
 return obj[prop]

 objects_set = set([get_prop(o, prop) for o in objects])
 return [[o for o in objects if get_prop(o, prop) == obj] for obj in objects_set]
