Instead of cluttering the code with a whole bunch of local imports, for
such a short program I'd recommend just importing entire modules (skip
the specific symbols) at the top of the file.

Is the `newline` part actually necessary? Doesn't "\n" automatically
get translated into whatever it needs to be, assuming stdout is opened
in text mode?
