how to get the sum of palindromes to be palindrome in python code example

Example 1: palindrome number + python

number=int(input("Enter any number :"))
#store a copy of this number
temp=number
#calculate reverse of this number
reverse_num=0
while(number>0):
    #extract last digit of this number
    digit=number%10
    #append this digit in reveresed number
    reverse_num=reverse_num*10+digit
    #floor divide the number leave out the last digit from number
    number=number//10
#compare reverse to original number
if(temp==reverse_num):
    print("The number is palindrome!")
else:
    print("Not a palindrome!")

Example 2: palindrome python

#A palindrome is a word, number, phrase, or other sequence of characters which reads the same backward as forward.
#Ex: madam or racecar.
def is_palindrome(w):
	if w==w[::-1]: # w[::-1] it will reverse the given string value.
		print("Given String is palindrome")
	else:
		print("Given String is not palindrome")

is_palindrome("racecar")
