Not quite. "All you get" is python script with, say '#!/usr/bin/python'
loading the packaged modules.  And *not* a binary executable.  

And guess what: all that exists for R too via littler and Rscript.  Maybe
start here

   http://dirk.eddelbuettel.com/code/littler.html

and look at all the examples here

   http://dirk.eddelbuettel.com/code/littler.examples.html

and in the repo

   https://github.com/eddelbuettel/littler/tree/master/inst/examples

You then deploy packages using Rcpp just any of the other R packages.

Yes, it was an off-topic question.
