代碼無法在python中的elif中達到else語句

其他條件未執行。我無法在else語句之後打印數據。我得到輸出RESP = []，而不是RESP [0] = - 1代碼無法在python中的elif中達到else語句

爲什麼我收到這是存在在我的代碼::

考慮下面的代碼片段

任何錯誤

它什麼時候會用'val'調用它不檢查？ –

你可以用'switch'而不是'if..elif'來代替Python嗎？ – Virbhadrasinh

@Virbhadrasinh？可能要仔細檢查... – jonrsharpe

checkit("0x00") # makes the else branch executed

checkit（0）將只執行其他塊，但我需要爲True和False條件運行的代碼。 – Chandra

將「0x00」添加到「li」列表中怎麼辦？ – dlask

這是工作，如果我把其他條件後，如果條件，但最後我不知道爲什麼？
