>>> import datetime
>>> old_tuple = (
...     datetime.datetime(2007, 8, 1),
...     datetime.datetime(2007, 8, 2),
...     1,
...     2.0,
...     3.0,
...     4
... )
>>> first_date = old_tuple[0].strftime('%Y-%m-%d')
>>> second_date = old_tuple[1].strftime('%Y-%m-%d')
>>> new_tuple = (first_date, second_date) + old_tuple[2:]
>>> print '\t'.join(str(i) for i in new_tuple)
2007-08-01      2007-08-02      1       2.0     3.0     4

Without more information that's the best I can think of.
