類“__”的未決議屬性參考“_

我正在上一門初學者課程，當我到達這里時，講師為課程制作了一個單獨的檔案，然后將其匯入。我剛剛在頂部添加了這個類，因為我以前見過它作業。雖然它不像這樣作業，但從另一個檔案匯入它是有效的。我究竟做錯了什么？

運行程式時的完整錯誤訊息：

您正在將Class物件串列傳遞給 RunTest 函式。

當您遍歷此串列時，請參考當前物件的.question和.answer屬性。

def RunTest(questions):
    score = 0
    for question in questions:
        ans = input(question.question)
        if ans == question.answer:

uj5u.com熱心網友回復：

這是因為您需要首先創建該類的實體，

例子：

>>> class MyClass:
...    def __init__(self,question,answer) -> None:
...        self.question = question
...        self.answer = answer

您需要首先將類實體化為一個物件：

>>> myobject = MyClass(question="how good is potato",answer="delicious")

那么你可以呼叫self.question：

>>> myobject.question
"how good is potato"
>>> myobject.answer
"delicious"
