import random
word_list = ['ardvark', 'baboon', 'camel']
word = random.choice(word_list)
riddle = len(word) * '_'
print(riddle)
while '_' in riddle:
guess = input('Guess a letter: ').lower()
for letter in word:
index = (word.index(guess))
if letter == guess:
riddle[index] = letter
print(riddle)
導致
riddle[index] = letter
TypeError: 'str' object does not support item assignment
我知道我知道，字串是不可變的，但仍然......為什么？它們是可索引的，因此如果應用適當的解決方法，這可能會以某種方式起作用。或不？

制作謎語串列，然后在需要時不使用分隔符列印它
riddle = list(len(word) * '_')
print(*riddle, sep="")

在 python（和其他一些語言）中，字串是不可變的。解決方法是改用串列：
import random
word_list = ['ardvark', 'baboon', 'camel']
word = random.choice(word_list)
riddle = ['_'] * len(word)
print(''.join(riddle))
while '_' in riddle:
guess = input('Guess a letter: ').lower()
for letter in word:
index = (word.index(guess))
if letter == guess:
riddle[index] = letter
print(''.join(riddle))

你可以用這種方式重新定義謎語。但是，如果您猜測單詞中不包含的字母，您還應該更好地捕捉到錯誤。
import random
word_list = ['ardvark', 'baboon', 'camel']
word = random.choice(word_list)
riddle = len(word) * '_'
print(riddle)
while '_' in riddle:
guess = input('Guess a letter: ').lower()
for letter in word:
index = (word.index(guess))
if letter == guess:
riddle = riddle[:index] letter riddle[index 1:]
print(riddle)
