Python list built-in type method

List action Methods
Action on List L
For example
List = range (1,5) #即 list=[1,2,3,4], with no last element
List = range (1, ten, 2) #即 list=[1, 3, 5, 7, 9]

List.append (obj)
Add a new object at the end of the list
2 List.count (obj)
Count the number of occurrences of an element in a list
3 List.extend (SEQ)
Append multiple values from another sequence at the end of the list (extend the original list with a new list)
4 List.index (obj)
Find the index position of the first occurrence of a value from the list
5 List.insert (index, obj)
Inserting an object into a list
6 List.pop ([Index=-1])
Removes an element from the list (the last element by default), and returns the value of the element
7 List.remove (obj)
To remove the first occurrence of a value in a list
8 List.reverse ()
Reverse List of elements
9 List.sort (Cmp=none, Key=none, Reverse=false)
Sort the original list

Del List[1] #删除指定下标的元素
Del List[1:3] #删除指定下标范围的元素12345
Del List # Deletes list, then list does not exist

List[1:] =list # list = [2,3,4] Slice operator for sub list extraction
LIST[2] # Read the third element in the list
List[-2] #读取列表中倒数第二个元素
List[1:] # Starting from the second element to intercept a list
List1 = list[:] #list1为list的克隆, that is, another copy *

CMP (List1, List2) #比较两个列表的元素
Len (list) #列表元素个数
Max (list) #返回列表元素最大值
Min (list) #返回列表元素最小值
List (seq) #将元组转换为列表

3 in [1, 2, 3] True #元素是否存在于列表中
For x in [1, 2, 3]: print x, #1 2 3 iterations
[2]* 4 #表示为 [2,2,2,2]
