why 'double tuple' when using %s with print?

[jkndeja at my-deja.com]

Hello there
    Here's a relatively simple question. If t is a tuple

>>> t = (1,2)

then I can print it with

>>> print t

to get the result. If I want to print is using the '%' operator,
I try

>>> print "my tuple is %s" % t

but this gives me
   TypeError: not all arguments converted

and I have to use

>>> print "my tuple is %s" % (t,)

to get what I expect.

Shurely, since t is already a tuple, it shouldn't need to be converted
into a 'tuple of tuples'?

Thanks for any explanation
