OK, I've just read back over the whole thread. I'm really struggling to understand what point you're trying to make. I started out by saying:
> Use a list when you need an ordered collection which is mutable (i.e. > can be altered after being created). Use a tuple when you need an > immutable list (such as for a dictionary key). To which you obviously objected. So now you write: > I think a tuple is an immutable sequence of items, and a list is a > mutable sequence of items. So how is that different from what I said? Is this whole argument boiling down to your use of "immutable sequence" vs. my use of "immutable list"? -- http://mail.python.org/mailman/listinfo/python-list
