string which need to be conerted into date fromat which i am not able
to do so please help me.

from datetime import date

date_str_1 = '2006-01-10'
date_str_2 = '2005-12-15'
date_1 = date(*map(int, date_str_1.spli t('-')))
date_2 = date(*map(int, date_str_2.spli t('-')))
print (date_1 - date_2).days - 1

No that's not what I would calculate. I would do without the ``- 1`` but
the OP wanted 25 as result. Without the substraction it's 26. ;-)
