How many characters do you need to add to make a string a palindrome?

Question

Python

How can you use Python to find out what is the minimum number of characters that you need to assign to a string on the right or left so that it becomes a palindrome?

Answer 1

s = '1232'

for i in range(len(s)):
    t = s[:i] + s[::-1]
    if t == t[::-1]:
        print(i, t)
        break
