When it started to get to object orientation I started having problems following. It just didn't make sense. Maybe I should try again, but it just always made me feel that for my particular mind functional thinking was better.
life ← {⊃1 ⍵ ∨.∧ 3 4 = +/ +⌿ ¯1 0 1 ∘.⊖ ¯1 0 1 ⌽¨ ⊂⍵}
I'm not sure how you don't call that an eso lang.
def life(x):
y = np.array([np.roll(x, -1), np.roll(x, 0),np.roll(x, 1)])
y = np.array([np.roll(y, -1, 1), np.roll(y, 0, 1),np.roll(y, 1, 1)])
z = y.sum(1).sum(0)
a = np.array([3 == z, 4==z])
c = np.logical_and(np.array([np.ones(x.shape), x]), a)
return np.logical_or(c[0], c[1])
