I wrote the below code

    raise RuntimeError, 'This    code    is    not    secure    in    Python    2.2    and    later'
    def get1(name, object=object, filter=filter):
        'Internal    function    for    Bastion().        See    source    comments.'
        if filter(name):
            attribute = getattr(object, name)
            if (type(attribute) == MethodType):
                return attribute
        raise AttributeError, name
    def get2(name, get1=get1):
        'Internal    function    for    Bastion().        See    source    comments.'
        return get1(name)
    if (name is None):
        name = repr(object)
    return bastionclass(get2, name)

What's a good function header?

def Bastion(object, filter=(lambda name: (name[:1] != '_')), name=None, bastionclass=BastionClass):
