How can I show the guessed letters of a word guesser in order? Python

Question

I've been asked to create a word guesser in python which outputs to the user how many letters are in the word, for example python has 6, so it would output 6. Then the user has 5 guesses to guess what letters are in the word, after these 5 guesses, the user is meant to guess the word. I've been able to display what letters have been guessed correctly by concatenating them to a new string, but I've not been able to display the correct position of the word and also if the letter appears twice in the word, essentially like hangman.

Question 1: How can I get the letters guessed correctly to appear in the order of the word and not the order they are guessed in?

Question 2: How do I get a repeating letter to show however many times it appears in the word?

Code below:

#WordGuesser

import random

WORDS = ("computer","science","python","pascal","welcome")

word = random.choice(WORDS)
correctLetters = ""
guesses = 0

print(
    """

    Welcome to Word Guesser!
    You have 5 chances to ask if a certain letter is in the word
    After that, you must guess the word!

    """
)

print("The length of the word is", len(word))


while guesses != 5:
    letter = input("Guess a letter: ")

    if letter.lower() in word:
        print("Well done", letter, "is in the word")
        correctLetters += letter
        print("Correctly guessed letters are: ",correctLetters)
        guesses += 1


    else:
        print("No", letter, "is not in the word")
        correctLetters += "-"
        guesses += 1

guess = input("Please now guess a word that it could be!: ")

if guess == word:
    print("Well done, you guessed it")
    input("\n\nPress enter key to exit")

else:
    ("You did not guess it, the word was: ",word)

Answer 1

You should iterate over the word instead in order output the guessed letters in the word of the letters in the correct word. Use a set instead to keep track of the correct letters for efficient lookups since you only need it to determine whether or not a letter has been correctly guessed:

correctLetters = set()
while guesses != 5:
    letter = input("Guess a letter: ").lower()

    if letter in word:
        print("Well done", letter, "is in the word")
        correctLetters.add(letter)
        print("Correctly guessed letters are: ", ''.join(letter if letter in correctLetters else '-' for letter in word))

    else:
        print("No", letter, "is not in the word")
    guesses += 1
