Either escaped, or it can be the first character in the set.

I just checked PEP 8, and unfortunately this is not mentioned in there. Maybe
you could open a new issue (or post in a mailing list) to ask about which style
should be recommended, and then add the conclusion to PEP 8.

Getting the console width (and height) is something so common that I believe
there should be a built-in Python library for doing that. And it's also
something hard to do correctly (get COLUMNS variable, or use ioctl, or trap
SIGWINCH signal, or do something completely different on non-unix, or fallback
to hardcoded default or user-supplied default)
What's more, since built-in argparse module needs this feature, that is another
good reason to get it inside standard Python library. It has been proposed
before, but the issue was closed: #8408
Anyway, although I believe this is important, it is off-topic in this issue.
