Thanks, Chris, that helps a lot. It seems that beyond being a
programming language, Python has a well-established culture that
suggests how the language should be used. I am gathering that
understanding the language and embracing the existing culture are
needed to use Python in the way it is meant to be used, though the
language design allows *other* ways, too.
