TypeError：'in <string>' 左侧操作数需要字符串，而不是列表

Question

我正在为我的GCSE计算机项目制作一个猜单词游戏（也叫“吊死鬼”）。我遇到了一个错误，怎么也解决不了。

这是我写的全部代码：

import random

#Creates a tuple with words in
WORDS = ("church","smelly","chicks")


#This picks a word randomly
word = random.choice(WORDS)
print("The word is", len(word), "letters long.")


#This is the game
for i in range(1):
letter1 = input ("Guess a letter:")

if letter1 in word:
 print("Correct. This letter is in the word")
else:
 print("Incorrect. This letter is not in the word.")

for i in range(1):
letter2 = input ("Guess a letter:")

if letter2 in word:
 print("Correct. This letter is in the word")
else:
 print("Incorrect. This letter is not in the word.")

for i in range(1):
letter3 = input ("Guess a letter:")

if letter3 in word:
 print("Correct. This letter is in the word")
else:
 print("Incorrect. This letter is not in the word.")

for i in range(1):
 letter4 = input ("Guess a letter:")

if letter4 in word:
 print("Correct. This letter is in the word")
else:
 print("Incorrect. This letter is not in the word.")

for i in range(1):
letter5 = input ("Guess a letter:")

if letter5 in word:
 print("Correct. This letter is in the word")
else:
 print("Incorrect. This letter is not in the word.")

for i in range(1):
letter6 = input ("Guess a letter:")

if letter6 in word:
 print("Correct. This letter is in the word")
else:
 print("Incorrect. This letter is not in the word.")

all_letters = [letter1, letter2, letter3, letter4, letter5, letter6]

# Conditions for winning/losing
if all_letters in word:
 print("Well done, you got it.")
else:
 print("Sorry, You are the loser.")

当我运行程序时，出现了这个错误：

TypeError: 'in <string>' requires string as left operand, not list

我不知道该怎么修复这个错误，能不能请大家帮帮我？

另外，如果可以的话，能给我一些建议，告诉我哪里可以改进代码的某些部分吗？

*这是我第一次提问，如果我说得有点多，请多包涵。

你应该这样做：

if all(i in word for i in all_letters):
    print("Well done, you got it.")
else:
    print("Sorry, You are the loser.")

这样做的话，只有当所有字母都在单词里时，才会打印出 '干得好，你做到了.' 这个信息。这里用了一个叫 all 的内置函数。
