Huh?  I would prefer neither.  I would rather have

if errs:
  sys.exit(1)
sys.exit(0)

or even
  sys.exit(errs)
(which works just fine if 'errs' is a string, and it even prints
the message to stderr!)

and

style_names = {
  BOLD: "bold",
  ITALICS: "italics",
  UNDER: "undescore",
}

  print style_names[style]

or possibly even

  print style.name
