Question 6

Write a program to check if a number is present in the list or not. If the number is present, print the position of the number. Print an appropriate message if the number is not present in the list.

l = eval(input("Enter list: "))
n = int(input("Enter number to search: "))

if n in l:
    print(n, "found at index", l.index(n))
else :
    print(n, "not found in list")

Output

Enter list: [1, 3, 15, 8, 20]
Enter number to search: 15
