So... although the following is such a short list that I don't think it
really matters (except that, come to think of it, it is in a loop), it's bad
form?

if self.item[0:3] in ('Mon','Tue','Wed','Thu','Fri','Sat','Sun'):
	self.item = self.item[4:]

If it's not obvious, this is stripping the day abbreviation from the
beginning of a timestamp that I'm converting to another format.

I can't quite see how to use "while... not" to do what I want, however.
