Hello friend;

Try this:

datetime.datetime.strptime("01-11-2013", '%m-%d-%Y').strftime('%d/%m/%Y') 

prints "11/01/2013".

If you can't live with the leading zero, try this:

dt = datetime.datetime.strptime("2013-1-25", '%Y-%m-%d')

print '{0}/{1}/{2:02}'.format(dt.month, dt.day, dt.year % 100)

This prints "1/11/13" 

Best Regards.
