該Animal類中有3個實例屬性，分別是name，age和location，并且這3個屬性都是帶雙下劃線(__)前綴的，說明是私有屬性。私有屬性在類的外部不能被直接訪問，但可以在類的內部直接訪問，所以定義了六個方法分別獲取（get）和設置（set）這三個私有屬性的值，在類的外部可以通過這六個方法分別獲取或設置實例中這3個屬性的值。__init__實例方法是構造函數，在創建實例的時候可以方便同時設置實例的屬性的初始值。

執行最后有一個None,是因為python函數使用return返回值，如果不用return, 而用print輸出值，這個函數默認還有一個返回值為None .?

可以用私有屬性。1、 super（）._init_(param，param)這句話，調用了父類的初始化方法，那么如果需要傳父類初始化方法的全部參數，但可以設置默認參數，就可以不傳color這個參數，父類通過二個下劃線設置私有屬性。子類不能繼承。
