The 'main' function (resp. method) in C and Java has nothing to do with
a "mainloop" - it's just the program entry point, IOW the function that
will get called when the program is executed.
Python has no such thing, since all code at the top-level is executed
when the script is passed to the python runtime.
The notion of "mainloop" (or event loop) is specific to event-driven
programs, which, once everything is set up, enter in a loop, wait for
events to come, and dispatch them to appropriate handlers. And FWIW,
there's no loop in your above example - the main() function will call
procedures 1, 2 and 3 sequentially then exit.

You don't "call some functions" to "run the program" - you pass your
script to the python runtime, and all top-level code will be executed
sequentially.
