hashing an array - howto

[Helmut Jarausch]

Hi,

I need to hash arrays of integers (from the hash module).

So, I have to derive from array and supply a __hash__ method.
But how to hash an array (of fixed length, say 25)?
What I need is a function which maps a tuple of 25 integers
into 1 integer with good hashing properties.

Does anybody know such a thing?

Many thanks for a hint,
