Hi everybody! I was just smacked by some very surprising Python 2.7 behaviour. I was assembling some 2D points into a list:
points = [] points += (3, 5) points += (4, 6) What I would have expected is to have [(3, 5), (4, 6)], instead I got [3, 5, 4, 6]. My interpretations thereof is that the tuple (x, y) is iterable, so the elements are appended one after the other. Actually, I should have used points.append(), but that's a different issue. Now, what really struck me was the fact that [] + (3, 5) will give me a type error. Here I wonder why the augmented assignment behaves so much different. Can anyone help me understand this? Thanks!
