Scrabble wordgame error in python

Question

У меня возникли проблемы со словной игрой, которую я пытаюсь сделать, царапать.

Часть моего кода, где он в конечном итоге дает ошибку, является:

def is_valid_word(word, hand, word_list): 
""" 
Returns True if word is in the word_list and is entirely 
composed of letters in the hand. Otherwise, returns False. 
Does not mutate hand or word_list.

hand_copy = hand.copy() 
if word not in wordList: 
    return False 
for char in word: 
    if char not in hand_copy: 
     return False 
    else: 
     hand_copy[char] -= 1 
    if hand_copy[char] < 0: 
     return False 
return True 


def play_hand(hand, words):

* When a valid word is entered, it uses up letters from the hand. 
* After every valid word: the score for that word is displayed, 
    the remaining letters in the hand are displayed, and the user 
    is asked to input another word. 
* The sum of the word scores is displayed when the hand finishes. 
* The hand finishes when there are no more unused letters. 
    The user can also finish playing the hand by inputing a single 
    period (the string '.') instead of a word.

В моем opninion это должно работать. Я могу начать игру, разыграть новую руку, переиграть последнюю руку или закончить игру. Но когда я пытаюсь сделать слово из заданных букв дает эту ошибку:

Traceback (most recent call last): 
File "wordgames.py", line 257, in <module>

File "wordgames.py", line 163, in is_valid_word 
    if word not in wordList: 
NameError: global name 'wordlist' is not defined 

Я пытался много, но ничего не помогает ... Пожалуйста, кто-нибудь может помочь мне исправить эту проблему?

Заранее благодарен!

Ошибка четко указано в нижней части TRACEBACK:

File "wordgames.py", line 163, in is_valid_word 
    if word not in wordList: 
NameError: global name 'wordlist' is not defined 

т.е. вы не определяете wordList - входная переменная называется word_list.

Также вы должны исправить отступы в своем вопросе, чтобы дать понять, где заканчивается определение функции, и вы вернетесь в глобальную область.

Как jonsharpe указывает, ваш отслеживающий также противоречивы (wordlist вместо wordList)
