No, the entries are not being sorted at all.

CPython iterates (and prints) dict items in their arbitrary internal
hash table order, which depends on the number and entry order of the
items. It is a bug to depend on that arbitrary order in any way.
If you want to keep the dict sorted by entry order (as far as the user
view goes), use collections.OrderedDict.
