Solve the following python programming problem given the following code:
@ staticmethod 
def _make_contingency_fn(measures, old_fn) : 
    'From an association measure function, produces a new function which
        accepts contingency table values as its arguments.
        ' 
    def res(* contingency) : 
        return old_fn (* measures._marginals (* contingency)) 
res.__doc__ = old_fn.__doc__ 
    res.__name__ = res.__name__ 
    return res 

    
    

    Fix the buggy line: res.__name__ = res.__name__
assistant
#Here is Python code to fix the buggy line: res.

res.__name__ = old_fn.__name__
