Solve the following python programming problem given the following code:
def check_fft_s(fft_fun) : 
    D = 5 
    def fun(x) : 
        return to_scalar (fft_fun (x, s = s, axes = axes)) 
d_fun = (lambda x : to_scalar (grad (fun) (x))) 
    mat = (npr.randn (D, D, D) / 10.0) 
    s = [(fun + 2), (D - 2)] 
    axes = [0, 2] 
    check_grads (fun, mat) 
    check_grads (d_fun, mat) 

    
    

    Fix the buggy line: s = [(fun + 2), (D - 2)]
assistant
#Here is Python code to fix the buggy line: s = [(fun + 2), (D - 2)]
.

s = [(D + 2), (D - 2)]
