It's possible there are other factors that can affect this as well. A more general statement is probably more appropriate: "Keys and values are listed in an arbitrary order. This order is non-random, varies across Python implementations, and depends on the dictionary's history of insertions and deletions as well as factors outside the scope of the containing program." "Iteration over a set returns elements in an arbitrary order, which may depend on factors outside the scope of the containing program." --- -Bill Hamilton -- http://mail.python.org/mailman/listinfo/python-list
