title: want to find multiple of the same letter and replace it
body: <p>Creating hangman and was able to find a letter with index and replace it. After it replaces the letter,once i do the same letter, it knows its a correct letter,however does not replace. Example word is wood. (replaces first o, detects second o but does not replace in hidden)</p>
  <pre><code>#Selecting a letter and replacing hidden to show letter
  while correct_guess_amount &lt; len(word):
      print(hiding)
      guess_letter = input(&quot;enter a letter: &quot;)
  
      if guess_letter in word:
  
          position = word.index(guess_letter)
          hiding = hiding.replace(hiding[position], guess_letter)
  
          correct_guess_amount += 1
  
      else:
          incorrect_guess_amount += 1
          incorrectList += guess_letter
  </code></pre>
  <p>position = position of letter in word</p>
  <p>guess_letter = letter you are guessing</p>
  <p>hiding = the ____ or in my case the #@!$%</p>
