W0715 (raising-format-tuple)
Problematic code:
raise RuntimeError("This looks wrong %s %s", ("a", "b"))
Correct code:
raise RuntimeError("Maybe you meant this %s %s" % ("a", "b"))
Rationale:
Used when passing multiple arguments to an exception constructor, the first of them a string literal containing what appears to be placeholders intended for formatting.
