[Tutor] questions about tuples

[Fangwen Lu]

Dear all-

 I want to do some loops. Each loop will generate a tuple. Eventually I want
to put tuples together in a higher level of tuple. Do you know how to do
this?

Say a=(1,2,3), b=(4,3,2),c=(9,5,6). I want to get a tuple as ((1,2,3),
(4,3,2),(9,5,6)).

If there are just 2 tuples, I can write x=a and then x=(x,b). But for 3
tuples or more, I will get something like (((1,2,3), (4,3,2)),(9,5,6)).

Thanks.
