Yes it is. > The "1, 2" in "x[1, 2]" isn't evaluated according to the same rules as > in "x = 1, 2" I was pretty sure it was. > - for example, you can have "x[1, 2:3:4, ..., 5]", which > isn't a legal tuple outside of square braces Yes it is, it just is illegal notation outside square brackets. You could have approximate the same effect by I = 1, slice(2,3,4), Ellipsis, 5 x[I] > - in fact, it even isn't > legal inside parens: "x[(1, 2:3:4, ..., 5)]" isn't legal syntax. But what is illegal is the notation, not the value. -- Antoon Pardon -- http://mail.python.org/mailman/listinfo/python-list
