How to calculate number of days between two given dates?

Question

If I have two dates (ex. \'8/18/2008\' and \'9/26/2008\'), what is the best way to get the number of days between these two dates?

Answer 1

from datetime import date
def d(s):
  [month, day, year] = map(int, s.split('/'))
  return date(year, month, day)
def days(start, end):
  return (d(end) - d(start)).days
print days('8/18/2008', '9/26/2008')

This assumes, of course, that you've already verified that your dates are in the format r'\d+/\d+/\d+'.
