Finding all time periods for a given interval within a date range

Hi everyone,

I was wondering if anyone has written some Python code which uses a start
date and end date and a given interval (day, month or year) and outputs all
the time periods for that range and interval.

For example you may wish to find all the months between the dates
'2004-02-14' and '2004-08-04'. You would maybe use a function where you pass
in those starting and ending dates and the interval 'month' and you'd get
back a list of those months. I guess you would need to year part of the date
too, so ['2004-02', '2004-03', '2004-04', '2004-05', '2004-06', '2004-07',
'2004-08']. If you had passed in 'day' as the interval then you would be
given back a list of all the days in those months.

This is pretty specific but I would appreciate anything similar or even a
good pointing in the right direction of which modules to use. I've taken a
look at 'time' and 'calendar' but all I could see what the
'calendar.calendar' function which would require quite a bit of string
processing after getting the calendar strings.

Thanks for any help :-)
