datetime.iterdate

[Larry Bates]

List comprehension to the rescue:

day_range=[first+datetime.timedelta(x) for x in range((last-first).days+1))]
for day in day_range:
    do_something_with(day)

I'm not entirely sure the syntax is correct (I just
copied yours for the example) , but you get the idea.
I think it clearly defines the list of items you are
iterating over and keeps the definition close to the
loop where you do something (rather in a function
that may be defined far away in the code).

Anyone else tired of typing date-addition logic when iterating? It would
be nice if the datetime package had something like:

def iterdates(first, last):
    for day in range((last - first).days + 1):
        yield first + datetime.timedelta(day)

...notice the inclusive boundaries (i.e. last gets returned). This
simple construct would make ugly date loops a lot cleaner:

for day in datetime.iterdates(first_date, last_date):
   do_something_with(day)
