When you load Python code from a file, __file__ is the location of it on
disk. That works for modules you import as well. But in a frozen
application, the Python code isn't loaded from a file (in fact it's inside
a zip archive), so __file__ doesn't really make sense.

As Michael has pointed out, exit() isn't really a built-in. It's a
convenience function for using Python interactively, but in regular
programs, you should use sys.exit().

There are a few interactive conveniences like exit() - quit(), copyright,
license, credits - that you should avoid using in programs. Besides those,
I think __file__ is the only thing that's not available.

You may also need to be cautious about using sys.executable - normally it's
the Python interpreter you're running in, so you can call it to start a
subprocess with the same version of Python. In a frozen application, it
will be the executable that launches your application.
