Don't bother with a main() function unless you actually need to be
able to use it as a function. Most of the time, it's simplest to just
have the code you want, right there in the file. :) Python isn't C or
Java, and code doesn't have to get wrapped up in functions in order to
exist.
Not (necessarily) a main function, but these days the general
recommendation seems to be to use the "if __name__ == '__main__':"
construct, so that the file can be used as a module as well as as a
script. Even for short simple things that can be helpful when doing
things like running tests or extracting docstrings.

the movement of small green pieces of paper, which was odd because on the whole
it wasn't the small green pieces of paper that were unhappy."
