Solve the following python programming problem given the following code:
def _skip_decorator(func) : 
    @ functools.wraps (func) 
    def skip_if_not_implemented(* args, **kwargs) : 
        try : 
            return func (* args, ** kwargs) 
except tooz.NotImplemented as e : 
            raise testcase.TestSkipped (str (e)) 
return <MASK> 
    
    Given the code above, what is a proper replacement for <MASK>? Choose among: func
assistant
#Here is a proper replacement for <MASK>.
