List comprehensions-Wrong result

[RavCOder]

Hi,
I don't understand why this code that I have write didn't work:

if __name__ == '__main__':
    x = int(input())
    y = int(input())
    z = int(input())
    n = int(input())

new_list =[ [a,b,c] for a in range (0,x +1) for b in range (0,y +1) for c in (0,z +1) if a+b+c != n] 
print(new_list) 

Result :

[[0, 0, 0], [0, 1, 0], [0, 1, 2], [1, 0, 0], [1, 0, 2], [1, 1, 2]]

Correct result:

[[0, 0, 0], [0, 0, 1], [0, 1, 0], [1, 0, 0], [1, 1, 1]]
