    Context: building a consistent hashing algorithm.

    The official documentation for Python's hash() function states:


    Return the hash value of the object (if it has one). Hash values are integers.
    ​

    However, it does not explicitly state whether the function maps to an integer range (with a minimum and a maximum) or not.

    Coming from other languages where values for primitive types are bounded (e.g. C#'s/Java's Int.MaxValue), I know that Python's likes to think in "unbounded" terms – i.e. switching from int to long in the background.

    Am I to assume that the hash() function also is unbounded? Or is it bounded, for example mapping to what Python assigns to the max/min values of the "int-proper" – i.e. between -2147483648 through 2147483647?
