Pyfdate  http://www.ferg.org/pyfdate/index.html
has a numsplit function that should do the trick:
http://www.ferg.org/pyfdate/tutorial.html#contents_item_14

It splits a string into its numeric parts and return a list containing
the numeric parts converted to ints.

>>> from pyfdate import *
>>> numsplit("2007_10_09")
[2007, 10, 9]
>>> numsplit("2007-10-09T23:45:59")
[2007, 10, 9, 23, 45, 59]
>>> numsplit("2007/10/09 23.45.59")
[2007, 10, 9, 23, 45, 59]
