Can anybody help me and tells me what is the thing that is missing

class Palindrome:

  @staticmethod
  def is_palindrome(word):
    copy_ = word[-1:]
    if word == copy_:
       return True
     else:
       return False


  print(Palindrome.is_palindrome("deleveled"))

Change:

copy_ = word[-1:]

To:

copy_ = word[::-1]

word[-1:] just returns the last character of the word.

Replace 

copy_ = word[-1:]

with 

copy_ = word[::-1]

The [::-1] slice inverting the string

Another method is to use reverse function.

copy_ = ''.join(reversed(word))

Note: word[::-1] is faster.

  • @MihaiAlexandru-Ionut reason for `word[::-1]` being faster? – Jeru Luke May 07 '18 at 10:38

    @JeruLuke Timings (and the reasons for them) for various ways to implement reversing a string are given in https://stackoverflow.com/questions/931092/reverse-a-string-in-python. – BoarGules May 07 '18 at 12:06
