SilentGhost added the comment:
No, what this piece of code shows is that trying to assign a value to a tuple
element will cause an error. Of course, the same error would be raise when
using the the value 12345, but it's more instructive to use a different value
to not confuse the reader.
New submission from Ben Schreib:
The example given in section 5.3 shows an output of "t[0] = 8" but I
believe it should be "t[0] = 12345"
>>> t
(12345, 54321, 'hello!')
>>> # Tuples may be nested:
... u = t, (1, 2, 3, 4, 5)
>>> u
((12345, 54321, 'hello!'), (1, 2, 3, 4, 5))
>>> # Tuples are
