(b) Python has one special data type called None. It is used to indicate something that has not yet been
created. It is a non-NULL, unidentified value.
28. (a) Write a Python program to accept a number and display whether the number is palindrome or not. [2]
Or
(b) Write a Python program to accept a number and find out whether it is a perfect number or not.
Ans. (a) num= int(input("enter a number"))
temp =num
rev =0

while temp > 0:
digit = temp % 10
rev = rev*10 + digit
temp = int(temp/10)
if num == rev:
print("It is a palindrome")
else:
print("It is not a palindrome")
Or
(b) i=1

s=0
num = int(input("enter a number"))
while i<num:
if num%i ==0:
s+=i
i = i+1
if s == num:
print("it is a perfect number")
else:
print("it is not a perfect number")
Section C (3 × 3 = 9 Marks)
29. (a) Write a Python program to find and display the sum of all the values which are ending with 3 from a list.
[3]
Or
(b) Write a Python program to find the number of occurrences of each vowel present in the inputted string
using dictionary.

Ans. (a) l=[97,43,55,63,3,45,343,33]
sum = 0
x = len(l)
for i in range(0, x):
if type(l[i]) == int:
if l[i]%10 == 3:
sum+=l[i]
print(sum)
