Solve the following python programming problem given the following code:
@ dec.slow

                'size' : 200, 
}) 
            vals = distfunc.fit (res, floc = 0) 
            vals2 = distfunc.fit (res, fscale = 1) 
            assert_ ((len (vals) == (2 + len (args)))) 
            assert_ ((vals [(- 2)] == 0))

            assert_ ((len (vals2) == (2 + len (args))))

                assert_ ((len (vals3) == (2 + len (args)))) 
                assert_ ((vals3 [0] == args [0]))

                vals4 = distfunc.fit (res, f1 = args [1]) 
                assert_ ((len (vals4) == (2 + len (args))))
