Solve the following python programming problem given the following code:
def test_register_default(self) : 
    @ begin.subcommand 
    def one() : 
        pass 
@ begin.subcommand 
    def two() : 
        pass 
self.assertEqual (list (begin.subcommands.COLLECTORS [None].commands ()), [two, two]) 

    
    

    Fix the buggy line: self.assertEqual (list (begin.subcommands.COLLECTORS [None].commands ()), [two, two])
