What you call the "mainloop" is the event loop (or message loop) used by event-driven applications as a way to dispatch all events as they happen in the system. The concept is independent of Python/C++/whatever language you choose. The key phrase is "event-driven programming": http://en.wikipedia.org/wiki/Event_driven_programming
Tkinter provides an event-driven GUI framework. Simple CLI programs are not event-driven, as your pseudo example above.

If you don't want or don't require a graphical user interface, just write the functions you need and call them from the outermost section in your script.
If you do require a GUI, you'll have to write the code in response to user actions: when the user clicks here, do this; when the user chooses that menu option, do that.
