Upon further reflection, it may be that you're loading the code dynamically or something (and not just running it as a command line application) or something that caused the __main__ not to trigger.

Once I understood the constraint, I was fine. It's a neat little app, and for somebody who's never had an actual job as a programmer, some of these exercises I feel are things that I should at least know the pattern.

I'm digging it.

Thanks! The code is executed by an "host" script with a system call, not sure if this breaks the __main__ function in python. We will look into that issue. :)
