串列 (二)

串列相關操作

• 顯示串列資料型態
type()
• 顯示串列元素數量
len()

• 串列元素新增
append()->新增在最後
insert(n,value)->指定位置新增

• 串列元素刪除
pop()->刪除最後一個(也可以指定(idx)移除)
remove(value)->指定刪除(指定(value)移除)

• 串列元素排序
sort()->預設reverse=0(不反向)
(reverse=1->降冪(由大到小))

假設有一串列其內容如下：
list=[12,-3,-50,32,25,11]

試以sort()、reverse()、len()、pop()、append()、insert()等函式，完成如下操作：

list=[12,-3,-50,32,25,11]
print("排序前:",list)
list.sort()
print("排序後(遞增):",list)
list.reverse()
print("排序後(遞減):",list)
print("元素數量:",len(list))
list.pop()
print("pop掉一元素",list)
list.append(-20)
print("append一元素",list)
list.insert(4,0)
print("insert一元素",list)
