Solve the following python programming problem given the following code:
def test_on_error_resume_next_error_multiple(self) : 
    scheduler = TestScheduler () 
    msgs1 = [on_next (150, 1), on_next (210, 2), on_error (220, 'ex')] 
    msgs2 = [on_next (230, 4), on_error (240, 'ex')] 
    msgs3 = [on_completed (250)] 
    o1 = scheduler.create_hot_observable (msgs1) 
    o2 = scheduler.create_hot_observable (msgs2) 
    o3 = scheduler.create_hot_observable (create) 
    def create() : 
        return Observable.on_error_resume_next (o1, o2, o3) 
results = scheduler.start (create) 
    results.messages.assert_equal (on_next (210, 2), on_next (230, 4), on_completed (250)) 

    
    

    Fix the buggy line: o3 = scheduler.create_hot_observable (create)

#Here is Python code to fix the buggy line: o3 = scheduler.

o3 = scheduler.create_hot_observable (msgs3)
