Solve the following python programming problem given the following code:
def _test_set(self, typecallable, creator = None) : 
    if (creator is None) : 
        creator = self.entity_maker 
class Foo (object) : 
        pass 
canary = Canary () 
    instrumentation.register_class (Foo) 
    attributes.register_attribute (Foo, 'attr', uselist = True, extension = canary, typecallable = typecallable, useobject = True) 
    obj = Foo () 
    adapter = collections.collection_adapter (obj.attr) 
    direct = obj.attr 
    control = set () 
    def assert_eq() : 
        eq_ (set (direct), canary.data) 
        eq_ (set (adapter), canary.data) 
        eq_ (direct, control) 
def addall(* values) : 
        for item in values : 
            direct.add (item) 
            control.add (item) 
assert_eq () 
def zap() : 
        for item in list (direct) : 
            direct.remove (item) 
control.clear () 
addall (creator ()) 
    e = creator () 
    addall (e) 
    addall (e) 
    if hasattr (direct, 'remove') : 
        e = creator () 
        addall (e) 
        direct.remove (e) 
        control.remove (e) 
        assert_eq () 
        e = creator () 
        try : 
            direct.remove (e) 
except KeyError : 
            assert_eq () 
            self.assert_ ((e not in canary.removed)) 
else : 
            self.assert_ (False) 
if hasattr (direct, 'discard') : 
        e = creator () 
        addall (e) 
        direct.discard (e) 
        control.discard (e) 
        assert_eq () 
        e = creator () 
        direct.discard (e) 
        self.assert_ ((e not in canary.removed)) 
        assert_eq () 
if hasattr (direct, 'update') : 
        zap () 
        e = creator () 
        addall (e) 
        values = set ([e, creator (), creator ()]) 
        direct.update (values) 
        control.update (values) 
        assert_eq () 
if hasattr (direct, '__ior__') : 
        zap () 
        e = creator () 
        addall (e) 
        values = set ([e, creator (), creator ()]) 
        direct |= values 
        control |= values 
        assert_eq () 
        values = set ([e,...

    
    

    Fix the buggy line: values.update (set ([addall, creator ()]))

#Here is Python program to fix the buggy line: values.

values.update (set ([e, creator ()]))
