If you want to access an element of a tuple, you can use indices, in the same way you would an array or list:
result = (datetime.date(2007, 2, 9),)
date = result[0]
print date.strftime("%Y-%m-%d")
Or simply:
print result[0].strftime("%Y-%m-%d")
You can also assign a tuple to an set of variables to get its contents:
coords = (4, 6)
x, y = coords
And for a tuple with a single value:
result = (datetime.date(2007, 2, 9),)
date, = result
This notation when applied to only one value is a little obscure, however.
