'Renaming' duplicate items in a Python list

I am creating a word guessing game where a player needs to guess the secret word.

For each guess the user makes, I classify each letter of a guess to either of the following three categories:

Hot - The letter is in the right place when compared to the secret word.
Warm - The letter is in the secret word but not in the right place.
Cold - The letter is not in the secret word.

To do this, I have created a simple loop:

for i in range(len(guess)):
    if guess[i] in secret_word[i]:
        # Hot
    elif guess[i] in secret_word:
        # Warm
    else:
        # Cold

However, the problem with this loop is, for instance, the secret word is: apple, and the user inputs puppy. The loop returns:

Hot: [p]
Warm: [p, p]
Cold: [u, y]

The error(s):
1. We don't know which 'p' are the right/wrong ones.
So to fix this, I was planning to 'assign' them numbers corresponding to how many times they appear in the guess so that the output should be like below:

Hot = [p2]
Warm = [p1] # Since there are 2 remaining 'p's, we'll just take the first one
Cold = [p3, u, y]

This way, the user knows which letter and position they got right. Although, I have been trying to implement the above procedure in my code to no avail. I'll be really grateful if anyone can help me!

You can achieve this easier by using enumerate. This way you can access both index and letter and quickly compute if a letter is hot, warm or cold. Something like this:

secret = "apple"
guess = "puppy"

hot = []
warm = []
cold = []

for index, letter in enumerate(guess):
    if letter == secret[index]:
        hot.append(letter + str(index))
    elif letter in secret:
        warm.append(letter)
    else:
        cold.append(letter)

print(f"Hot: {hot};  Warm: {warm}; Cold: {cold}")

For your example this will output:

Hot: ['p2'];  Warm: ['p', 'p']; Cold: ['u', 'y']
