Simple hangman game using while and if-else loop does not iterate correctly

I am trying to design a hungman game using simple while loop and if else statement.

Rules of the game:

1.Random word is selected from a list of words

2.User is informed when the word is selected and asked to provide his/ her first guess

3.If the user's guess is correct, the letter is console and inform the user how many letters left

4. The user will get only 5 lives to play the game.

    1.import random
    2.import string
    3.def hungman():
    4.words = ["dog", "monkey", "key", "money", "honey"]
    5.used_letters = []
    6.word = words[random.randrange(len(words))]
    7.lives=5
    8.while len(word) > 0 and lives > 0:
        9.guess = input("Please guess the letter: ")
        10.if 'guess' in word:
           11.print(guess, " is a correct guess")
           12.used_letters.appened(guess)
           13.if used_letters.len == word.len:
               14.print("Congratulation, You have guessed the correct letter: ",word)      
           15.else:
               16.remaining_letters =  word.len - used_letters.len
               17.print("You have", remaining_letters, "left")
   
   
         18.else:
         19.lives = lives - 1
         20.if lives == 0:
             21.print("Sorry! you don't have more lives to continue the game")
             22.print("Correct word is: ", word)
             23.break
         24.else:
             25.print("You have", lives , " left")
   
    26.hungman()
   

The program should ask for the user input which will store in guess variable. If the letter given by the user is one of the letters of word string then the code prompts that the given input is correct and append the letter in the used_letters list. Else it shows the length of the remaining letters for wrong user input. Additionally, if the user fails to guess the letter correctly he or she will lose 1 life as well.

However, as per my code after the while loop in line number 8 the control goes to line no. 18 although I provided correct letter as user input. Line 10 to 17 totally discarded. I could not find the reason of this nature.

Please help me in this regard.

Thank you
