Hash of integers for use in Random module

[Will McGugan]

Hi,

If I retrieve the hash of an integer, will it always return the same
value across platforms?

This reason I ask is that I want to produce a sequence of pseudo random
numbers using the random module, that I can re-create later on. So I'll
need to store the seed value, but Random.seed takes a hashable object
rather than an integer directly.

Which brings another question to mind. Are hashes of builtin objects in
general consistent across platforms, or are they an implementation
detail that could change?

TIA,

Will McGugan

*sigh* Didnt read the docs closely enough. It does say that ints and
longs are used directly..
