Chapter 7.9, Problem 23CP

Program Plan Intro

Tuple:

• • A tuple is an object that has immutable sequence of elements.
• • The contents of the tuple cannot be altered once it is created, so tuples in Python are immutable.
• • Tuples have static size.
• • The elements of tuples can be of various types, i.e. tuples are heterogeneous.
• • Elements in the tuple are enclosed by parenthesis.

Syntax:

In python, a tuple is created using the below format:

#Create a tuple

Tuple_name = (element1, element2, …, elementn)

Explanation:

• • “Tuple_name” specifies the name of the tuple.
• • “element1, element2, and elementn” indicate the elements of the tuple “Tuple_name”.

Example program:

Consider the below example that creates a tuple and prints the tuple.

#Declare a tuple with numbers, strings

tuple_ex = [1, 'Joe', 'Tom', 4]

#Print the tuple

print(tuple_ex)

Sample Output:

[1, 'Joe', 'Tom', 4]

Program explanation:

In the above code,

• • “tuple_ex” represents a tuple having integers and strings as its elements.
• • Then, the tuple “tuple_ex” is printed using “print()” function.
