Alright, I'm stuck here. As far as I can tell, my code is nearly identical to Kenneth's, save for a few different variable names and a different word list. Here's my code, the problem appears to be in the 'play' function:
import sys
import os
import random
words = [
'lamp',
'moana',
'barbies',
'superhero',
'coconut',
'dash',
'wazowski',
'snowman',
'journal',
'carpet',
'jazzbone',
'iridocyclitis',
'ohana'
]
def welcome():
start = input("Press ENTER to start, or Q to quit. ").lower()
if start == 'q':
print('Bye!')
sys.exit()
else:
return True
def clear():
if os.name == 'nt':
os.system('cls')
else:
os.system('clear')
def draw(bad_guesses, good_guesses, secret_word):
clear()
print("Strikes: {}/7".format(len(bad_guesses)))
print('')
for letter in bad_guesses:
print(letter, end=' ')
print('\n\n')
for letter in secret_word:
if letter in good_guesses:
print(letter, end='')
else:
print('_', end='')
print('')
def get_guess(bad_guesses, good_guesses):
while True:
guess = input("Guess a letter! > ").lower()
if len(guess) != 1:
print("You can only guess one letter at a time.")
elif guess in bad_guesses or guess in good_guesses:
print("You've already guessed that letter.")
elif not guess.isalpha():
print("You can only guess letters!")
else:
return guess
def play(done):
clear()
secret_word = random.choice(words)
bad_guesses = set()
good_guesses = set()
word_set = set(secret_word)
while True:
draw(bad_guesses, good_guesses, secret_word)
guess = get_guess(bad_guesses | good_guesses)
if guess in word_set:
good_guesses.add(guess)
if not word_set.symmetric_difference(good_guesses):
print("You win!")
print("My secret word was {}.".format(secret_word))
done = True
else:
bad_guesses.add(guess)
if len(bad_guesses) == 7:
draw(bad_guesses, good_guesses, secret_word)
print("You lost!")
print("My secret word was {}.".format(secret_word))
done = True
if done:
play_again = input("Play again? Y for yes, N for no. > ").lower()
if play_again != 'n':
return play(done = False)
else:
print("Thanks for playing!")
sys.exit()
print("Welcome to Letter Guess!")
done = False
while True:
clear()
welcome()
play(done)
I'd like to thank anyone in advance that takes the time to help me. My problem is that when I run the game in the shell, I get this error:
Traceback (most recent call last):
File "letter_game_2.py", line 124, in <module>
play(done)
File "letter_game_2.py", line 86, in play
guess = get_guess(bad_guesses | good_guesses)
TypeError: get_guess() missing 1 required positional argument: 'good_guesses'
I'm not quite sure what this means. Thanks again to anyone willing to help me figure this out, it would be greatly appreciated.

# ^ I think this is the problem, it should be a comma

You were right, the problem is in the "play" function, in the second line of the "while" loop.

5,675 PointsThanks Wesley. That seems to be what Kenneth had, but I'm probably missing something there. Changing it to a comma made it run perfectly.
