import datetime

def daysOfWeek(year, week):
    day = datetime.date(year, 2, 1)
    year, weekBase, dayBase = day.isocalendar()
    day += datetime.timedelta(1 - dayBase + (week - weekBase)*7)
    delta = datetime.timedelta(1)
    for i in range(6):
        yield day
        day += delta
    yield day

Try it:

>>> from daysofweek import daysOfWeek
>>> for d in daysOfWeek(2004, 1):
...     print d
