input: Write a python function to check if a given string is a palindrome.
  assert is_palindrome("radar") == "The given string is a Palindrome"
  assert is_palindrome("python") == "The given string is not a Palindrome"
  assert is_palindrome("level") == "The given string is a Palindrome"
output: def is_palindrome(s):
      if s == s[::-1]:
          return "The given string is a Palindrome"
      else:
          return "The given string is not a Palindrome"
