write a function that returns a palindrom in python when ? replaced with lowercse letters code example

Example 1: string palindrome in python

n = input("Enter the word and see if it is palindrome: ") #check palindrome
if n == n[::-1]:
    print("This word is palindrome")
else:
    print("This word is not palindrome")

Example 2: palindrome without using string function in python

n = input("eNTER  STRING\n")
length = int(len(n))
n = str(n)

for i in range(0, int(length/2+1)):
   if n[i] != n[-i - 1]:
      break

if i < int(length/2 + 1):
   print("not")
else:
   print("yes")
