What do you mean by 'indicate'? Writing it to the docstring of the class/method? Writing a comment? class Foo: """ When inheriting from Foo, method foo must be overridden. Otherwise SPAM. """ def foo(self): print 'bar' class Bar(Foo): def __init__(self): Foo.__init__(self) # Has to be defined to override the base class's method # when inheriting from class Foo. Otherwise: SPAM def foo(self): print 'foo' I don't know any other way. Thomas -- http://mail.python.org/mailman/listinfo/python-list
