IMHO you got more than a bit lost. You seem to have stumbled on a
possibly unintended side effect of re.split.
What is your underlying goal?
If you want merely to split on '-', use datum.split('-').
If you want to verify the split results as matching patterns (4
digits, 2 digits, 2 digits), use something like this:
| >>> import re
| >>> datum = '2008-03-14'
| >>> pattern = r'^(\d\d\d\d)-(\d\d)-(\d\d)\Z'
You may notice two differences between my pattern and yours ...
| >>> mobj = re.match(pattern, datum)
| >>> mobj.groups()
| ('2008', '03', '14')
But what are you going to do with the result? If the resemblance
between '2008-03-14' and a date is not accidental, you may wish to
consider going straight from a string to a datetime or date object,
e.g.
| >>> import datetime
| >>> dt = datetime.datetime.strptime(datum, '%Y-%m-%d')
| >>> dt
| datetime.datetime(2008, 3, 14, 0, 0)
| >>> d = datetime.datetime.date(dt)
| >>> d
| datetime.date(2008, 3, 14)
