I'm trying to find the letter_game.py file but could not find it.

in the workspace for the video. Look under the Workspaces tab below the video near the Teacher's Notes.
For convenience, I've copied the file below:
import random
words = [
'apple',
'banana',
'orange',
'coconut',
'strawberry',
'lime',
'grapefruit',
'lemon',
'kumquat',
'blueberry',
'melon'
]
while True:
start = input("Press enter/return to start, or Q to quit ")
if start.lower() == 'q':
break
secret_word = random.choice(words)
bad_guesses = []
good_guesses = []
while len(bad_guesses) < 7 and len(good_guesses) != len(list(secret_word)):
for letter in secret_word:
if letter in good_guesses:
print(letter, end='')
else:
print('_', end='')
print('')
print('Strikes: {}/7'.format(len(bad_guesses)))
print('')
guess = input("Guess a letter: ").lower()
if len(guess) != 1:
print("You can only guess a single letter!")
continue
elif guess in bad_guesses or guess in good_guesses:
print("You've already guessed that letter!")
continue
elif not guess.isalpha():
print("You can only guess letters!")
continue
if guess in secret_word:
good_guesses.append(guess)
if len(good_guesses) == len(list(secret_word)):
print("You win! The word was {}".format(secret_word))
break
else:
bad_guesses.append(guess)
else:
print("You didn't guess it! My word was {}".format(secret_word))

On the other hand, I have a question about this block of code:
while len(bad_guesses) < 7 and len(good_guesses) != len(list(secret_word)):
I understand the 'and' logic function but not the logic of
len(good_guesses) != len(list(secret_word)):
[MOD: added ```python formatting -cf]

Treehouse Moderator 68,441 PointsThe code fragment:
len(good_guesses) != len(list(secret_word)):
If the length of good_guesses
(that is, the number of correctly guessed letters) is not equal to the number of letters in the secret_word
then it is implied that there are some letters left to guess so the game must continue.
There is a subtle flaw in this logic. If the secret_word
has a repeated letter as in, say, "apple", the number guessed letters ["a", "p", "l", "e"] (4) will never equal the length of the secret_word
"apple (5) so the game will never end correctly.
There is a mention of this error in one of the teacher's notes, and I believe Kenneth corrects this error in later videos. One solution is to use set
instead of list
to count the number of unique letters in secret_word
.
