Hi,

I am absolutely new in Python and just stuck with this below problem.

X,Y and Z are the three coordinates of a cuboid. Now X=1,Y=1 , Z=1 and N=2.

I have to print a list of all possible coordinates on a 3D grid where the sum of Xi + Yi + Zi is not equal to N. If X=2, the possible values of Xi can be 0, 1 and 2. The same applies to Y and Z.

```
results = []
sets = []
for x in range(X):
for y in range(Y):
for z in range(Z):
if(int(x+y+z) != N):
sets.append(x)
sets.append(y)
sets.append(z)
results.append(sets)
```

Could any one please help me out with the proper way of doing it using list comprehension?
