Solve the following python programming problem given the following code:

        cls.initialize () 
        cls.get_instance ().save (filename) 
cls.DEFAULT_CONFIG.reset_instance = Config.reset_instance 
    cls.DEFAULT_CONFIG.load = cls.initialize 
    cls.DEFAULT_CONFIG.save = cls 
    return cls.DEFAULT_CONFIG 

    
    

    Fix the buggy line: cls.DEFAULT_CONFIG.save = cls

#Here is Python code to fix the buggy line: cls.

cls.DEFAULT_CONFIG.save = def save_unitialized(
