Solve the following python programming problem given the following code:
def check_poly(self, func, cls, param_ranges = [], x_range = [], nn = 10, nparam = 10, nx = 10, rtol = 1e-08) : 
    np.random.seed (1234) 
    dataset = [] 
    for n in np.arange (nn) : 
        params = [(a + ((b - a) * np.random.rand (nparam))) for (a, b) in param_ranges] 
        params = np.asarray (params).T 
        if (not dataset) : 
            params = [0] 
for p in params : 
            if param_ranges : 
                p = ((n,) + tuple (p)) 
else : 
                p = (n,) 
x = (x_range [0] + ((x_range [1] - x_range [0]) * np.random.rand (nx))) 
            x [0] = x_range [0] 
            x [1] = x_range [1] 
            poly = np.poly1d (cls (* p)) 
            z = np.c_ [(np.tile (p, (nx, 1)), x, poly (x))] 
            dataset.append (z) 
dataset = np.concatenate (dataset, axis = 0) 
    def polyfunc(* p) : 
        p = ((p [0].astype (int),) + p [1 :]) 
        return func (* p) 
olderr = np.seterr (all = 'raise') 
    try : 
        ds = FuncData (polyfunc, dataset, list (range ((len (param_ranges) + 2))), (- 1), rtol = rtol) 
        ds.check () 
finally : 
        np.seterr (** olderr)
