How to increment date by week Iin python. ..

Question

Starting on any day/date, I would like to create a one year list, by week (start date could be any day of week). Having a numerical week index in front of date, ie 1-52, would be a bonus.
ie, 1. 6/4/2013
2. 6/11/2013
3. 6/18/2013....etc to # 52.

And to save that result to a file. Moving from 2.7 to 3.3

Answer 1

from datetime import date, timedelta

the_date = date(year=2013, month=6, day=4)

print "%d. %s" % (1, the_date)

for n in range(2, 53):
the_date = the_date + timedelta(days=7)
print "%d. %s" % (n, the_date)

Answer 2

import datetime
start = datetime.date.today()
for i in range(53):
dt = start + datetime.timedelta(days=7*i)
result = "%i. %s" % (
i+1,
dt.strftime('%m/%d/%Y')
)
do_something_with(result)
