I'm using the dateutil module from http://labix.org/python-dateutil.
Am I right in thinking that the rrules module doesn't acknowledge days
before today?

I'll answer my own post.
If you don't specify dtstart, it defaults to datetime.today().
Therefore, there are no instances before today. Specify dtstart as a
historic date, and it works on any dates after dtstart.
Wish I'd engaged brain before posting.

You don't really need regexes for this.
Assuming there is no whitespace in any of your values, it should be
really easy to parse the string.
s = 'x:11 y:0 w:760 h:19 area:14440 areaPerCent:0
totalAreaPerCent:-3.08011e+16 type:3 path:///-/1/1'

Your solution Steven Bethard looks very intelligent, here is a small
speed test, because sorting a list according another one is a quite
common operation.
(Not all solutions are really the same, as Alex has shown).
from itertools import izip, imap
from operator import itemgetter
from random
This is probably faster:
def alfa_(w):
return w.replace(_, a).isalpha()
This is another solution, but it's probably slower, you can time it:
from string import letters
_setalpha = set(letters + _)
def alfa_2(w):
return not (set(w) - _setalpha)
