need help with some fundamentals of for loops. it looks like im so close to fully grasping grabbing an item out of a list, but not quite. examples below

        import random
    word_list = ["aardvark", "baboon", "camel"]
    chosen_word = random.choice(word_list)
    
    #Testing code
    print(f'Pssst, the solution is {chosen_word}.')
    
    #Create an empty List called display.
    #For each letter in the chosen_word, add a "_" to 'display'.
    #So if the chosen_word was "apple", display should be ["_", "_", "_", "_", "_"] with 5 "_" representing each letter to guess.
    

    display = ["_"] * len(chosen_word)
    
    
    guess = input("Guess a letter: ").lower()
    
    #If the letter at that position matches 'guess' then reveal that letter in the display at that position.
    #e.g. If the user guessed "p" and the chosen word was "apple", then display should be ["_", "p", "p", "_", "_"].
    
    for letter in chosen_word:
    if guess == letter:
    for i in range(len(chosen_word)):
    display.insert(i, guess)
    
    print(display)


  

        for letter in chosen_word:
      if guess == letter:
        for i in range(len(chosen_word[letter])):
          display.insert(i, guess)
    
    I ended up just saying screw it and went to this:
    
    display = []
    for char in chosen_word:
        if guess == letter:
            display += letter
       else:
        display += "_"



  

        import random
    word_list = ["aardvark", "baboon", "camel"]
    chosen_word = random.choice(word_list)
    
    print(f'Pssst, the solution is {chosen_word}.')
    
    display = []
    word_length = len(chosen_word)
    for _ in range(word_length):
      display += "_"
    print(display)
      
    guess = input("Guess a letter: ").lower()
    
    
    for position in range(word_length):
      letter = chosen_word[position]
      if letter == guess:
        display[position] = letter
    
    print(display)
