Why?  Split the string up, convert the parts to `int` and just create a
`datetime.date` object.

In [421]: '1/2/2005'.split('/')
Out[421]: ['1', '2', '2005']

In [422]: map(int, '1/2/2005'.split('/'))
Out[422]: [1, 2, 2005]

In [423]: month, day, year = map(int, '1/2/2005'.split('/'))

In [424]: a = datetime.date(year, month, day)

In [425]: b = datetime.date.today() - a

In [426]: b.days
Out[426]: 1017

Maybe you should read the docs next time.  ;-)
