Tis seems very nice solution but also we need to check the user input for validity. What if the user entered: 29 15 2013 ?

i tried to use your method applying some date validation check but that also failed for me:

try:
       if( datetime.strptime(date, '%d m% %Y') ):
	    day, month, year = int(date[:2]), int(date[3:5]), int(date[6:])
            date = date(year, month, day)
	    date = date.strftime('%Y-%m-%d')
except:
        print "....."
========================

Isn't method strptime check the user input for validity?
