打印結果：
my
name
is
mark
age
18
3、添加元素：append、extend、insert
append：向列表添加元素，添加到尾部
實例：
list=["my","name","is","mark","age",18]
print("添加前：",list)
list.append("test")
print("添加后：",list)
打印結果：
添加前： ["my", "name", "is", "mark", "age", 18]
添加后： ["my", "name", "is", "mark", "age", 18, "test"]
extend：將另外一個列表的元素逐一添加到指定列表中
實例：
list=["my","name","is","mark","age",18]
print("extend前：",list)
list2=["A","B"]
list.extend(list2)
print("extend后：",list)
打印結果：
extend前： ["my", "name", "is", "mark", "age", 18]
extend后： ["my", "name", "is", "mark", "age", 18, "A", "B"]
inset(index,objectA)：在指定位置index前面插入對象objectA
實例：
list=["my","name","is","mark","age",18]
print("insert前：",list)
list.insert(3,"test")
print("insert后：",list)
打印結果：
insert前： ["my", "name", "is", "mark", "age", 18]
insert后： ["my", "name", "is", "test", "mark", "age", 18]
4、修改元素：通過下標修改指定位子元素
實例：
list=["my","name","is","mark","age",18]
print("修改前：",list)
list[len(list)-1]=19
print("修改后：",list)
結果：
修改前： ["my", "name", "is", "mark", "age", 18]
修改后： ["my", "name", "is", "mark", "age", 19]
5、查找元素：in、not in、index、count
in、not in查找指定元素是否存在，或者不存在
實例：
list=["my","name","is","mark","age",18]
print("mark" in list)
print("Mark" in list)
print("mark" not in list)
print("Mark" not in list)
結果：
True
False
False
True
index:查找指定元素是否存在，存在返回下標，不存在返回-1
語法：list.index(目標對象[,開始下標,結束下標])
實例：
list=["my","name","is","mark","age",18]
print(list.index("name"))
print(list.index("name",0,2))
print(list.index("name",1,3))
結果：
1
1
1
count:返回指定對象在列表中出現的次數
實例：
list=["my","name","is",18,"mark","age",18]
print(list.count(18))
print(list.count("mark"))
print(list.count(19))
結果：
2
1
0
6、刪除元素：del、pop、remove
del：根據下標刪除pop：刪除最后一個元素，相當于彈出棧頂元素，如果指定下標，也可以刪除任意位置元素。
remove：根據元素的值進行刪除，只刪除最先找到的那個
實例：
list=["my","name",18,"is",18,"mark","age",18]
print("刪除前：",list)
del list[1]
print("del后：",list)
list=["my","name",18,"is",18,"mark","age",18]
list.pop()
print("pop后：",list)
list=["my","name",18,"is",18,"mark","age",18]
list.pop(0)
print("pop(0)后：",list)
list=["my","name",18,"is",18,"mark","age",18]
list.remove(18)
print("remove后：",list)
結果：
刪除前： ["my", "name", 18, "is", 18, "mark", "age", 18]
del后： ["my", 18, "is", 18, "mark", "age", 18]
pop后： ["my", "name", 18, "is", 18, "mark", "age"]
pop(0)后： ["name", 18, "is", 18, "mark", "age", 18]
remove后： ["my", "name", "is", 18, "mark", "age", 18]
7、排序：sort、reverse、sorted
sort：將數組從小到大排序，參數reverse=True可改成從大到小排序，永久排序reverse：將數組倒置，永久排序
sorted：效果同sort，只不過是臨時排序
實例：
list=[1,3,5,2,7,8,4,0]
print("排序前：",list)
list.sort()
print("sort后：",list)
list=[1,3,5,2,7,8,4,0]
list.sort(reverse=True)
print("sort(reverse=True)后：",list)
list=[1,3,5,2,7,8,4,0]
list.reverse()
print("reverse后：",list)
list=[1,3,5,2,7,8,4,0]
sorted(list,reverse=True)
print("sorted后（臨時操作不影響原有列表）：",list)
list=[1,3,5,2,7,8,4,0]
print("sorted后：",sorted(list,reverse=True))
結果：
排序前： [1, 3, 5, 2, 7, 8, 4, 0]
sort后： [0, 1, 2, 3, 4, 5, 7, 8]
sort(reverse=True)后： [8, 7, 5, 4, 3, 2, 1, 0]
reverse后： [0, 4, 8, 7, 2, 5, 3, 1]
sorted后（臨時操作不影響原有列表）： [1, 3, 5, 2, 7, 8, 4, 0]
sorted后： [8, 7, 5, 4, 3, 2, 1, 0]
8、列表最大值、最小值、總和：min、max、sum
實例：
list=[1,3,5,2,7,8,4,0]
print("列表最小值：%d"%min(list))
print("列表最大值：%d"%max(list))
print("列表總和：%d"%sum(list))
結果：
列表最小值：0
列表最大值：8
列表總和：30
