I'm having some slight trouble understanding exactly why this creates an infinite loop:
L = [1, 2] L.append(L) In a highly abstract way, I understand it. But if I were asked to write down what I think L is after the second line executes, I would write: [1, 2, [1, 2]] But the correct answer seems to be: [1, 2, [1, 2 [1, 2 [ ....... I guess what confuses me is that there doesn't seem to be anything inherent in L itself that would cause this repeat. If you add L to L, why don't you just get two Ls? Where does the cycle begin? Is this just a quirk that comes with having a variable include a reference to the same object the variable references? -- http://mail.python.org/mailman/listinfo/python-list
