In Java, for example, the @Override annotation not only provides compile-time checking of an override but makes for excellent self-documenting code.

Like others have said unlike Java there is not @Overide tag however above you can create your own using decorators however I would suggest using the getattrib() global method instead of using the internal dict so you get something like the following:
def Override(superClass):
def method(func)
getattr(superClass,method.__name__)
return method
If you wanted to you could catch getattr() in your own try catch raise your own error but I think getattr method is better in this case.
Also this catches all items bound to a class including class methods and vairables
