## Question:

8.9 Code Practice

Write a program that uses the following initializer list to find if a random value entered by a user is part of that list.
v = [24, 20, 29, 32, 34, 29, 49, 46, 39, 23, 42, 24, 38] The program should ask the user to enter a value. If the value is in the array, the program should print the index. If it is not in the array, the program should print -1.

The program which prints the index value of an enters number is written thus in python 3 ;

v = [24, 20, 29, 32, 34, 29, 49, 46, 39, 23, 42, 24, 38]

#list of values

num = int(input())

#prompts user to enter a value

a = [v.index(num) if num in v else -1]

#checks if number Is in array an stores the index in variable a else it stores 1

print(a)

#display the value of a

A sample run of the program is attached

They will be able to hopefully assist the student deal with the question by making use of the questions and answer examples. You can then have a discussion with your classmate and continue the school learning by studying the subject as a group.
