Sorry to pipe in so late, but this is actually the default behaviour of my C implementation (which I call KIO (Key Insertion Order), there is an option to change this to KVIO (Key (or) Value Insertion Order), which moves the pair to the end. Anthon Armin Ronacher wrote:

Conceptually, I would expect the following behaviour:
od = odict() od[1] = 'spam' # insert a new key od[2] = 'parrot' # insert a new key od[1] = 'ham' # modify existing key od.items() [(1, 'ham'), (2, 'parrot')] That behavior is different to any ordered-dict implementation out there ;-)
