Execute yes, but not necessarily allow access to the source if that is 
the problem.

It can certainly be made harder than simply distributing source code. By 
using a proprietary byte-code for example, or code designed to run on 
some virtual machine. The tools run execute it will need to be provided, 
but that's a long way from being able to reconstruct source code (and if 
that was achieved, you would likely end up with some source code that 
corresponds to the interpreter, not the application).

But it depends on what secrets the OP is trying to hide. Just proving 
.pyc files might be enough, and is minimal inconvenience to the user.
