If you "dump trivial debug infos" to stdout, you just break anything
relying on stdout being for *normal* program outputs - IOW, you just can
chain-pipe programs no more. As far as I'm concerned, it's *way* more
impolite than "alerting" the user. Also and FWIW, most programs have
--quiet and --verbose options that let the user specify verbosity.

If it's for a "quick hack job", you don't even need anything like what
the OP describe. For anything more serious - anything that requires more
than one .py script file with a couple functions and a main section -,
the couple minutes spent setting up a default logger will very quickly
But YMMV, of course...
