Would you prefer something like this numpy then?
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])
