Actually, all you've done is obscure your code. This is a very common
fallacy; people think that since they cannot themselves read the code
out of what they're distributing, nor can anyone else. There's no way
to completely stop people from reading your code other than to not
give them the code.

If you truly want to protect your code from prying eyes, therefore,
there's only one way to do it: host it on a server, and let people
access the server without seeing the code. This is true of all
languages, not just Python, and it's always been the way. You can try
to put legal guards around your code ("opening this package
constitutes acceptance, blah blah, you agree that you will not reverse
engineer, disassemble, blah blah"), but that won't stop people. It's
best to either give them the code and let them see it clearly (open
source) or keep the code away from them in all forms (server-side
deployment).
