Chapter 7, Problem 2TF

Explanation of Solution

Python tuples:

• • A sequence that cannot be altered or changed is said to be immutable sequence, whereas a sequence which can be altered or changed is said to be mutable sequence.
• • Python tuples are immutable, which means the data in the tuples cannot be altered.
• • Tuples support all the operations and functions as lists; however, tuples do not support those that alter their contents such as “append()”, “insert()”, “remove()”, and “del”.
• • The values of the tuple element cannot be updated or changed. However, for updating a tuple, take a portion of existing tuples for creating new tuples.

Example program:

#Create tuple

t1 = (1, 2);

#Tuples do not support indexing expression for assignment

#t1[1] = 3;

#Create another tuple

t2 = ...
