I have this string:

'2012-02-10' # (year-month-day)

and I need it to be as date type for me to use the date function isoweekday().

Does anyone know how I can convert this string into a date?

You can do that with datetime.strptime()

Example:

>>> from datetime import datetime

>>> datetime.strptime('2012-02-10' , '%Y-%m-%d')

datetime.datetime(2012, 2, 10, 0, 0)

>>> _.isoweekday()

You can find the table with all the strptime directive here.

To increment by 2 days if .isweekday() == 6, you can use timedelta():

>>> import datetime

>>> date = datetime.datetime.strptime('2012-02-11' , '%Y-%m-%d')

>>> if date.isoweekday() == 6:

... date += datetime.timedelta(days=2)

...

>>> date

datetime.datetime(2012, 2, 13, 0, 0)

>>> date.strftime('%Y-%m-%d') # if you want a string again

'2012-02-13'
