list源碼

? 列表簡介：
o 列表是序列對象，可包含任意的Python資料資訊，如字串、數字、列表、元組等
o 列表的資料是可變的，我們可通過對象方法對列表中的資料進行增加、修改、刪除等操作
o 可以通過list(seq)函數把一個序列類型轉換成一個列表
1．append(x)，在列表尾部追加單個對象x，使用多個參數會引起異常

     append(self, p_object)

1. 2. 3. 4.

>>>lst=[1,2,3] >>>relust=lst.append(4) >>>print result [1,2,3,4]

2.count(x)，返回對象x在列表中出現的次數
3.extend(L)，將列表L中的表項添加到列表中，返回None
4.Index(x)，返回列表中匹配對象x的第一個清單項目的索引，無匹配元素時產生異常
5.insert(i,x)，在索引為i的元素前插入對象x，如list.insert(0,x)在第一項前插入對象，返回None
6.pop(x)，刪除列表中索引為x的表項，並返回該表項的值，若未指定索引，pop返回列表最後一項
7.remove(x)，刪除列表中匹配對象x的第一個元素，匹配元素時產生異常，返回None
8.reverse()，顛倒列表元素的順序
9.sort()，對列表排序，返回none，bisect模組可用於排序清單項目的添加和刪除
