cx_Freeze and Py2exe both work as far as freezing the python code to an .exe and including all the different modules, but they are just as easy to unfreeze. With Py2exe you can use PyInstaller to retrieve the .py files (or .pyc - I can't recall which) and the same is also true with cx_Freeze, so it works as far as packaging your program as a standalone exe, but does not protect the source code.
