Python's datetime module is great, but it lacks some of the more obvious functionality that would be helpful for anyone manipulating dates. This includes adding a month to the current date, and parsing the date and time from a string.
While these things may be achievable with datetime and a several lines of code, I feel it's much more pythonic to have some crazy module that fulfills your hearts desire, and does so in one line of code or less.
I used it in my GnomeAdamInternetApplet.
