python - how to convert string to datetime.timedelta()?

Question

how can i convert my string of date to a datetime.timedelta() in Python?

I have this code :

import datetime

date_select = '2011-12-1'
delta = datetime.timedelta(days=1)
target_date = date_select + delta
print target_date

thanks in advance ...

You wouldn't convert date_select to a timedelta, instead, you need a datetime object, which can be added to a timedelta to produce an updated datetime object:

from datetime import datetime, timedelta

date_select = datetime.strptime('2011-12-1', '%Y-%m-%d')
delta = timedelta(days=1)
target_date = date_select + delta
print target_date

Or, if you prefer, without the fancy from ... import ... import line:

import datetime    # <- LOOK HERE, same as in your example

date_select = datetime.datetime.strptime('2011-12-1', '%Y-%m-%d')
delta = datetime.timedelta(days=1)
target_date = date_select + delta
print target_date
