can't compare datetime.datetime to datetime.date

Question

I have the following code and am getting the above error. Since I'm new to python I'm having trouble understanding the syntax here and how I can fix the error:

if not start or date < start: start = date 

Answer 1

There is a datetime.date() method for converting from a datetime to a date.

To do the opposite conversion, you could use this function datetime.datetime(d.year, d.month, d.day)

Answer 2

You can use the datetime.datetime.combine method to compare the date object to datetime object, then compare the converted object with the other datetime object.

import datetime  dt1 = datetime.datetime(2011, 03, 03, 11, 12) day = datetime.date(2011, 03, 02) dt2 = datetime.datetime.combine(day, datetime.time(0, 0))  print dt1 > dt2
