Python implementation of Jenkins Hash?

Does there exist a native Python implementation of the Jenkins hash algorithm(s)?

I need a hash algorithm that takes an arbitrary string and turns it into an 32-bit integer. For a given string, it must guarantee to return the same integer across platforms.

I have looked at the ELF hash algorithm, of which I have found a Python implementation. Could this be a suitable replacement given the above criteria? (http://www.partow.net/programming/hashfunctions/#ELFHashFunction)
