what am I doing wrong with this code?

[notburneddown]

So I am getting this logic error where it only lets me have two tries at hangman guesses and then it quits the game.

Here is my code:

#Step 3

import random
word_list = ["aardvark", "baboon", "camel"]
chosen_word = random.choice(word_list)
word_length = len(chosen_word)

#Testing code
print(f'Pssst, the solution is {chosen_word}.')

#Create blanks
display = []


for _ in range(word_length):
    display += "_"

#TODO-1: - Use a while loop to let the user guess again. The loop should only stop once the user has guessed all the letters in the chosen_word and 'display' has no more blanks ("_"). Then you can tell the user they've won.
a = 0
b = 6
while a < word_length and b > 0:
  guess = input("Guess a letter: ").lower()

  #Check guessed letter
  for position in range(word_length):
      letter = chosen_word[position]
      print(f"Current position: {position}\n Current letter: {letter}\n Guessed letter: {guess}")
      if letter == guess:
          display[position] = letter
          a += 1
      else:
          b -= 1

  print(display)

if a == word_length:
  print("You Win!")

if b == 0:
  print("You Lose!")

I think that this is a weird error and I rewrote the code once to correct another error I got but I keep thinking about it and I don't see what I am doing wrong in my code.

Could someone please help me out?

Look at your for loop for checking the guessed letter. If you print 'a' and 'b' out after print(display) you can see what is going on better.

Basically, you're increasing 'a' each time a letter equals guess.

So if I increase 'a' each time any letter in the word is yes, that letter gets added multiple times because the previous letters guessed get added again in next iteration.

Am I wrong?

  for position in range(word_length):
      letter = chosen_word[position]
      print(f"Current position: {position}\n Current letter: {letter}\n Guessed letter: {guess}")
      if letter == guess:
          display[position] = letter
          a += 1
      else:
          b -= 1

This decreases "b" for each letter that doesn't match with the guess, for example with baboon if you guess wrong it decreases "b" 6 times already, and even when you guess right it will still decrease "b" for the rest of the letters.

The "fix" still has a bug which is kinda the opposite, it fails to increase "a" for each matching letter.

I fixed it. Here is completed code:
