爲什麼功能沒有定義python

Question

首先，我想說，即時通訊noob當涉及到代碼。我在學校攻讀CS學位和Python是我的第一語言。我應該創建一個動物園類，根據我提供的參數輸出信息。由於某種原因，我不能得到這個編譯和即時通訊甚至不知道我做任何正確的事情。我的老師老師正在度假，所以子老師真的很有幫助。謝謝你們

你玩弄你的__init__()定義，然後你打電話時，他們失去了一些東西。

如果要以標準方式創建各種動物對象，則必須以標準方式定義它們。使用kid, animalType, legs, age, feature但kid, legs, age, animalType, feature不會允許您這樣做（並且我建議使用標準self來引用對象的實例，而不是kid）。

當您嘗試創建動物時，您正在提供它的類型，腿的數量和年齡，但是您從未告訴構造函數feature是什麼。其他人在程序的頂部附近定義（順便提一下，我建議將類定義從循環中取出），但feature無處可查。以某種方式定義它，或者完全忽略對feature（即使用類似kid1= Cub(kind, legs, age)之類的內容）的引用以降低默認值。
