Python Hangman Program Error

HEllo this is Gulshan Negi Well, I am writing a program for making hangman game in python but it shows some error at the time of execution, I don't know what wrong I am doing. Here is my source code:

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:
          guessed.append(guess)
          count += 1:
          if count == 1:
              time.sleep(1)
              print('   _____ \n'
                    '  |      \n'

I don't know what I am missing in coding. Can anyone give their suggestions on this. Thanks

I suppose this is a spam post. Will remove that user.

I am sorry but I must know about it that how this post comes under spam. Thanks

Ok that sounds like a real user :)

I just wonder about a Python question in a forum for HeidiSQL?

Thanks a lot for your kind response.

Well, since few days I was researching about it on the Google and I found that this post and I found that there was some problem in below code: There is a syntax error in the code in the line count += 1: This line should simply be count += 1 Thanks
