[在第102和103行，print(len(guess))和if len(guess) != 1:'guess'突出显示，并说“ Expected'Sized'，得到'（）-> str相反...'”我认为这与实际错误有关... idk

完整错误：

Traceback (most recent call last):
    File "/Users/...", line 142, in <module>
       get_guess()
    File "/Users/...", line 102, in get_guess
       print(len(guess))
TypeError: object of type 'builtin_function_or_method' has no len()

Answer 1

您的错误在这里：

guess = input('\nYour guess: ').lower
print(len(guess))

您已将lower函数（不是调用它的结果，而是内置函数本身）分配给了变量guess。然后尝试找到它的长度。您找不到函数的len，因此会收到该错误。
将第一行更改为：
guess = input('\nYour guess: ').lower()

将其作为由[[calling lower函数产生的字符串。
