Hi Dimitri,

here's one way:

 >>> my_tuple = (('goat', 90, 100), ('cat', 80, 80), ('platypus', 60, 
800))
 >>> my_sliced_tuple = tuple([x[0:2] for x in my_tuple])
 >>> my_sliced_tuple
(('goat', 90), ('cat', 80), ('platypus', 60))
 >>>

BTW, don't use `tuple' as a name. You can, but then you hide the 
built-in tuple function. And, you need that :-)

Best,
