Comparing two date strings in Python

Use datetime.datetime.strptime:

>>> from datetime import datetime as dt
>>> a = dt.strptime("10/12/13", "%m/%d/%y")
>>> b = dt.strptime("10/15/13", "%m/%d/%y")
>>> a > b
False
>>> a < b
True
>>>

If you like to use the dateutil and its parser:

from dateutil.parser import parse

date1 = parse('10/12/13')
date2 = parse('10/15/13')

print date1 - date2
print date2 > date2
