Python abbreviated string record

Question

Can anyone explain to me how another way to write ans. I don't know how it works written in one line.

X = int(raw_input())
Y = int(raw_input())
Z = int(raw_input())
N = int(raw_input())
ans = [[i, j, k] for i in range(X + 1) for j in range(Y + 1) for k in range(Z + 1) if i + j + k != N]
print ans

You want is in one line? `print([[i, j, k] for i in range(int(input()) + 1) for j in range(int(input() + 1) for k in range(int(input() + 1) if i + j + k != int(input()])`? (translated into python 3) — mozway, Apr 07 '22 at 18:22
@Sören ans = [[i, j, k] for i in range(X + 1) for j in range(Y + 1) for k in range(Z + 1) if i + j + k != N] how to write another way, normally — Pedja Mirkovic, Apr 07 '22 at 18:23
nested list comprehensions like this are never very readable IMO — Chris_Rands, Apr 07 '22 at 18:23
As a beginner you should not be investing time in learning Python 2. Those of us who still work in it do so because we have to support or migrate legacy code. — BoarGules, Apr 07 '22 at 21:08

I think this is what you meant:

X = int(raw_input())
Y = int(raw_input())
Z = int(raw_input())
N = int(raw_input())
ans = []

for i in range(X + 1):
    for j in range(Y + 1):
        for k in range(Z + 1):
            if i + j + k != N:
                ans.append([i, j, k])
print ans

Please correct me if I'm wrong
