I've never seen a code obfuscation scheme I thought did the job the
whole way, including compiling C, and Python bytecode is significantly
easier to turn back into something resembling the original source
(YMMV, I suppose). Also, if you don't know about common tools like
distutils, the odds are pretty good that it isn't your code itself
that is valuable to you- you're probably more interested in protecting
your idea about what the code should do. At least for now, that's
outside of the scope of technical solutions- discuss it with a lawyer,
not a programmer.

...no. Distutils is handy because you could just bundle your
dependencies and hand them an easy-to-install package, which would be
a quick way to get everybody on the same page. Of course, depending on
the licenses those dependencies are under you might want to do even
more talking to a lawyer than I've previously suggested before you go
about trying to sell that bundle- I'm sure you wouldn't want to 'rip
off' great free projects like python and numpy.
