Indexing, trimming and other tuple operations

Access to tuple elements, element extraction and operations are performed analogously to strings. Let's look at several examples:

>>> b = (3, 4, 5, 'a')

>>> b [0]

3

>>> b [-1]

'to'

>>> b [0: 3]

(3. 4. 5)

>>> t = ('the', 'tuples', 'are', 'immutable')

>>> t [0]

'the'

>>> t [1] = 'lists'

Traceback (most recent call last):

File "<stdin>", line 1, in <module>

TypeError: 'tuple' object does not support item assignment

The static or immutable characteristic of the tuples is observed, as are the strings. We can include tuples within tuples and concatenate and repeat them, such as string,

>>> b = (3, 4, 5, 'a')

>>> c = (b, 2)

>>> b + c

(3, 4, 5, 'a', (3, 4, 5, 'a'), 2)

>>> 3*b

(3, 4, 5, 'a', 3, 4, 5, 'a', 3, 4, 5, 'a')
