from datetime import datetime

a = datetime(2016,10,06,0,0,0)
b = datetime(2016,10,01,23,59,59)

a-b
# datetime.timedelta(4, 1)

(a-b).days
# 4
(a-b).total_seconds()
# 518399.0

from datetime import datetime
datetime_for_string = datetime(2016,10,1,0,0)

datetime.strftime(datetime_for_string,datetime_string_format)
# Oct 01 2016, 00:00:00
