Helmut Jarausch: > I need to hash arrays of integers (from the hash module).
One of the possible solutions is to hash the equivalent tuple, but it requires some memory (your sequence must not be tuples already): assert not isinstance(somelist, tuple) hash(tuple(somelist)) This is an alternative solution, it doesn't use much memory, but I am not sure it works correctly: from operator import xor hash(reduce(xor, somelist)) Bye, bearophile -- http://mail.python.org/mailman/listinfo/python-list
