我想完成我的程序我添加一個菜單，允許用戶選擇幾個選項，允許用戶在列表中存儲網站名稱和密碼。但是，當我將一些網站名稱和密碼附加到它們各自的保管庫時，出現了一個問題，當我嘗試在追加網站名稱和密碼後選擇一個選項時，例如「1」是預期的輸入以調用viewapp（ ）功能來查看迄今存儲的網站和密碼。事情是調用viewapp（）函數需要兩次以上的時間，它會拒絕第一個期望的輸入，但會奇怪地接受第二個輸入。同樣，當我選擇第三個選項來調用summary（）時，整個打印的摘要將打印兩次，這與菜單中僅接受第二個預期輸入的模式類似。該程序正在做我想做的事情，除了這個惱人的bug之外，在選擇這四個選項時，它會在第二次請求輸入時立即跳轉到該函數。幫助將不勝感激。Python：被要求輸入兩次並輸出重複的打印語句
