IndexError: list index out of range
你能告訴我這是什么原因嗎？為什么串列有問題？我添加這個是因為 stackoverflow 希望我添加更多詳細資訊：我嘗試使用該軟體中的基本類方法構建測驗，但遇到了問題。
uj5u.com熱心網友回復：
在displayQuestion方法中你呼叫guess方法。在guess方法中增加questionsIndex值，然后再次呼叫displayQuestion方法。
這個程序不斷重復，無限重復，直到questionIndex完成out of range。看來您需要displayQuestion從方法中洗掉呼叫該guess方法。
