## OOP：面向對象編程
- 實現了數據屬性和行爲屬性的融合
- 類：具有相同屬性的對象集合
- 實例/對象：類的一個具體實現
- 方法：就是在類中定義的函數
### 組合
- 兩個類有明顯的不同
- 一個類的屬性是另一個類的實例，用組合
### 子類
- 兩個類非常相似，只是有一些不同
- 通過一個類派生出另一個類，也可以說一個類繼承於另一個類
### 多重繼承
- 子類可以有多個父類
- 子類自動繼承所有父類的方法
- 對象查找方法時，按自下向上、自左向右的方式查找
### 特殊方法
- 爲了實現類的內部功能，python定義了很多以雙下劃線開頭、結尾的方法
- 這些方法被稱作magic魔法方法
