Hello this is gulshan negi

Well, I am writing a program for making a hangman game proposal, but it shows some errors at the time of execution. I don't know what I am missing here.

Source List: 

import random 
import time 
import os 


def play_again(): 
  question = 'Do You want to play again? y = yes, n = no \n' 
  play_game = input(question) 
  while play_game.lower() not in ['y', 'n']: 
      play_game = input(question) 

  if play_game.lower() == 'y': 
      return True 
  else: 
      return False 


def hangman(word): 
  display = '_' * len(word) 
  count = 0 
  limit = 5 
  letters = list(word) 
  guessed = [] 
  while count < limit: 
      guess = input(f'Hangman Word: {display} Enter your guess: \n').strip() 
      while len(guess) == 0 or len (guess) > 1:
          print('Invalid input. Enter a single letter\n') 
          guess = input( 
              f'Hangman Word: {display} Enter your guess: \n').strip() 

      if guess in guessed: 
          print('Oops! You already tried that guess, try again!\n') 
          continue 

      if guess in letters: 
          letters. remove(guess) 
          index = word. find(guess) 
          display = display[:index] + guess + display[index + 1:] 

      else:

   print('Thanks For Playing! We expect you back again!')

if __name__ == '__main__': 
  play_hangman()

Can anyone give their response on this, what I am missing here in coding.

Thanks
