Core Python Programming (2nd Edition)

Like numbers and strings, tuples are immutable, which means you cannot update them or change values
of tuple elements. In Sections 6.2 and 6.3.2, we were able to take portions of an existing string to
create a new string. The same applies for tuples.
>>> aTuple = aTuple[0], aTuple[1], aTuple[-1]
>>> aTuple
(123, 'abc', (7-9j))
>>> tup1 = (12, 34.56)
>>> tup2 = ('abc', 'xyz')
>>> tup3 = tup1 + tup2
>>> tup3
(12, 34.56, 'abc', 'xyz')
How to Remove Tuple Elements and Tuples
Removing individual tuple elements is not possible. There is, of course, nothing wrong with putting
together another tuple with the undesired elements discarded.
To explicitly remove an entire tuple, just use the del statement to reduce an object's reference count. It
will be deallocated when that count is zero. Keep in mind that most of the time one will just let an object
go out of scope rather than using del, a rare occurrence in everyday Python programming.
