Solve the following python programming problem given the following code:
def test_tvtk_scene_garbage_collected(self) : 
    scene_collected = [] 
    scene_weakref = None 
    def scene_collected_callback(weakref) : 
        scene_collected.append (True) 
def do() : 
        scene = TVTKScene () 
        reference = weakref.ref (scene, scene_collected_callback) 
        scene.close () 
        return reference 
with restore_gc_state () : 
        gc.disable () 
        scene_weakref = do () 
self.assertTrue (scene_weakref [0]) 

    
    

    Fix the buggy line: self.assertTrue (scene_weakref [0])
assistant
#Here is Python program to fix the buggy line: self.

self.assertTrue (scene_collected [0])
