Stuck on Rosalind Python Village - Variables and Some Arithmetics : http://rosalind.info/problems/ini2/

Given: Two positive integers a and b, each less than 1000.
Return: The integer corresponding to the square of the hypotenuse of the right triangle whose legs have lengths a and b

ex)for dataset 3,4 return 25

the dataset is always different for every trial. 

    a=859
    b=938
    print( a**2 + b**2 )

I've tried this code on my computer, and it worked. But Rosalind won't take it. What might be wrong in this code?
