Even if they have different hashes, they can be stored in the same underlying list before they are retrieved. Then, an actual comparison is done to check if the given key (i.e. object instance, not hash) is the same as one of the stored keys.
but, as I have already mentioned, comparison of oofun(s) via __le__, __eq__ etc doesn't change their inner state (but the methods can create additional oofun(s), although).

Дата: 16 марта 2013, 11:33:39my objects (oofuns) definitely have different __hash__() results - it's just integers 1,2,3 etc assigned to the oofuns (stored in oofun._id field) when they are created.Usually when you store something in a dict and later you can't find it anymore, it is that the internal state changed and that the hash is not the same anymore.Hi,Different objects can have the same hash, so it compares to find the actual correct object.
D.Matthieu2013/3/16 Dmitrey <tmp50@ukr.net>Дата: 15 марта 2013, 22:54:21no, their state doesn't change for operations like __le__ . AFAIK searching Python dict doesn't calls __le__ on the object keys at all, it operates with method .__hash__(), and latter returns fixed integer numbers assigned to the objects earlier (at least in my case).On 3/15/2013 3:34 PM, Dmitrey wrote: > the suspected bugs are not documented yet I'm going to guess that the state of the F_i changes when you use them as keys (i.e., when you call __le__.It is very hard to imagine that this is a Python or NumPy bug.
