I may have posted about this awhile back, but it came up as a real question for a man wanting to party the day his dog caught up and passed him in age, assuming one human year = seven dog years. It makes a fun Python program as it involves dates, which are notoriously problematic. Hint: Julian dates might come in handy, plus don't forget leap years. Another posing of the problem: Every day I live counts as 1 day, every day a dog lives counts as 7. Given a dog born later than myself (date), and my birthday (date), on which day will my dog and I have the same number of days to our credit (date)? I.e. date samecount ( date dog_bday, date my_bday ) Note: my newest gig involves teaching SQL using Python in shell mode to start (import MySQLdb **), per my standard pedagogy: http://worldgame.blogspot.com/2007/08/sa-pedagogy.html This courseware is proprietary by mutual consent, so I won't be saying much more about it here (or anywhere). Just more of the usual day job.
