Python implemented Java hashCode methods.
>>> import jhashcode
>>> print jhashcode.hashcode('hello world')
1794106052
>>> print jhashcode.hashcode(u'僕と契約して、魔法少女になってほしい！')
640953514
>>> print jhashcode.hashcode(0)
0
The results should be the same with Java.
Now int, str or unicode hash function is ready.
