It calls the `__hash__()` method on the object that was given as argument.
So there's not *the* hash function, but every type implements its own.

Fallback is the hash of the identity of an object:

In [415]: class A(object): pass
   .....:

In [416]: a = A()

In [417]: hash(a)
Out[417]: 161029068

In [418]: hash(id(a))
Out[418]: 161029068
