I think mpi4py is the best option.  It is a very nice implementation
and the developer is working really hard to make it a great package.
Also, I don't think pympi and pypar are being developed actively
anymore.

Another thing you might check out is IPython's parallel computing
facilities that let you use mpi4py (and other mpi bindings)
interactively:

I have never used BPS, but am familiar with the model.  Can probably
get it working interactively with IPython as well.

Cheers,

Brian
