The Next Palindrome number

Question

I am beginner in programming, So can you please tell me what\'s wrong with my code?

I want to print next palindrome number if the number entered by the user (n) is n

Answer 1

def next_palin_drome(n):
    while True:
        n+=1
        if str(n) == str(n)[::-1]:
            return n 

n=12231
print(next_palin_drome(n))

output:12321
