Get (year,month) for the last X months

Question

I got a very simple thing to to in python: I need a list of tuples (year,month) for the last x months starting (and including) from today. So, for x=10 and toda

Answer 1

Using relativedelta ...

import datetime
from dateutil.relativedelta import relativedelta

def get_last_months(start_date, months):
    for i in range(months):
        yield (start_date.year,start_date.month)
        start_date += relativedelta(months = -1)

>>> X = 10       
>>> [i for i in get_last_months(datetime.datetime.today(), X)]
>>> [(2013, 2), (2013, 1), (2012, 12), (2012, 11), (2012, 10), (2012, 9), (2012, 8), (2012, 7), (2012, 6), (2012, 5)]
