[Tutor] Tuple

[Kaushal Shriyan]

Hi All

I am referring to http://www.ibiblio.org/obp/thinkCSpy/chap09.htm

>>> tuple = ('a', 'b', 'c', 'd', 'e')
>>> tuple[0]
'a'


And the slice operator selects a range of elements.

>>> tuple[1:3]
('b', 'c')


But if we try to modify one of the elements of the tuple, we get a error:

>>> tuple[0] = 'A'
TypeError: object doesn't support item assignment


Of course, even if we can't modify the elements of a tuple, we can
replace it with a different tuple:

>>> tuple = ('A',) + tuple[1:]
>>> tuple
('A', 'b', 'c', 'd', 'e')

How does tuple = ('A',) + tuple[1:]  this work ????

Please explain me with an example

Thanks
