There's a python tool called "Freeze" out there. I've never used it, only heard references to it, but I think it does what you're looking for. Keep in mind that python was not intended to build executables, it was designed as a scripting language, so YMMV.

You could distribute only "compiled" python files (.pyc or .pyo). It's not impossible to figure out the internals of your program, but it makes it difficult to do so.

From the python tutorial:

Quote:

# It is possible to have a file called spam.pyc (or spam.pyo when -O is used) without a file spam.py for the same module. This can be used to distribute a library of Python code in a form that is moderately hard to reverse engineer.

# The module compileall can create .pyc files (or .pyo files when -O is used) for all modules in a directory.

And, of course, anything can be reverse engineered.

I mean, you can convert binarys to assembly language and hack at that, and there are decompilers for virtually every language. It's just a matter of how hard you're going to make it for them.

If this is being done for a company, why are you not providing them with the source? (Unless it's contract work, in which case you should be able to get away with a strong license: companies do try to stay on the legal side of things)
