Tuples are like any other Python collection or sequence.
You can access by indexing into the tuple:

second = tup[1]   # zero based index

you can also iterate over them:

for index, item in enumerate(tup):
   print index, item
   if index = 1: second = item

And additionally collections can be 'unpacked':

one, two, three = (1,2,3)

These techniques also work with lists and strings.

So pick the method that suits you best.
