Note that hashing in python 2.7 and prior to 3.4 is simply broken and
the randomization does not do nearly enough, see

Hey folks,
I hope this is the right list for this sort of thing (python-ideas seemed
more far-fetched).
For some context: there is currently a issue with pex that causes
sys.modules lookups to stop working for __main__. In turns this makes
unittest.run() & pkg_resources.resource_* fail. The root
I thought you are right. Here is the source code in python 2.7.11:
long
PyObject_Hash(PyObject *v)
{
PyTypeObject *tp = v->ob_type;
if (tp->tp_hash != NULL)
return (*tp->tp_hash)(v);

Yes. There's only one hash function used, which operates on byte
streams IIRC. That function now has a random offset. The details of
hashing each type are in the serializations t

Recent Python versions randomize the hashes of str, bytes and
