I found pyhash library. pyhash.murmur3_32() solved the problem. http://code.google.com/p/pyfasthash/ http://code.google.com/p/smhasher/

If you don't mind dealing with long integers, you can simply add the absolute value of the minimum integer: hash(value) + sys.maxint + 1. In any case, i think it's better to use sys.maxint, instead of 2**32. > Will that be unique(near unique)? Want to make sure hashing someother string will not produce the same hash value. >> Just modulo the hash function `hash_value % (2**32)` >>> Is anyone aware of any non-cryptographic hash function whose value is only postive integer. Pythons inbuilt hash function is a signed integer. _______________________________________________ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers _______________________________________________ BangPypers mailing list BangPypers@python.org http://mail.python.org/mailman/listinfo/bangpypers
