Python 2.7 Get month from 2 months ago (i.e get '05' from todays date)

I'm sure there is an easy way to do this that I have missed with my efforts to find the answer.

Basically how do I get the number of month i.e '05' or '04' from n number of months ago?

Apologies if this was already answered but the questions I researched here could not answer my question.

Edit

There is no month parameter in timedelta, so this did not answer my question.

Martin answered my question perfectly!

While Martijn's answer is perfect for your specific question for anyone who stumbles across this answer looking for a date X months ago rather than just the month's number I would suggest using relativedelta from the third party module dateutil. I have found it quite helpful:

>>> from datetime import date
>>> from dateutil.relativedelta import relativedelta

>>> today = date.today()
datetime.date(2015, 7, 28)

>>> for i in range(13):
        print(today - relativedelta(months=i))
2015-07-28
2015-06-28
2015-05-28
2015-04-28
2015-03-28
2015-02-28
2015-01-28
2014-12-28
2014-11-28
2014-10-28

With some simple modular arithmetic:

from datetime import date

def months_ago(count):
    today = date.today()
    return ((today.month - count - 1) % 12) + 1

Demo:

>>> date.today()
datetime.date(2015, 7, 28)
>>> for i in range(13):
...     print(months_ago(i))
...
