List Source

? Introduction to the list:
The O list is a sequence object that can contain any Python data information, such as strings, numbers, lists, tuples, etc.
o The data of the list is variable, we can add, modify and delete the data in the list through the object method.
O you can convert a sequence type to a list by using the list (SEQ) function
1. Append (x), appending a single object x at the end of the list, using multiple arguments causes an exception

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), returns the number of times the object x appears in the list
3.extend (l), add the table entry in list L to the list, return none
4.Index (x), returns the index of the first list item in the list that matches object x, produces an exception if no matching element
5.insert (I,X), inserts an object x before the element indexed to I, such as List.insert (0,X) before the first item, returns none
6.pop (x), removes the table entry with index x in the list and returns the value of the table entry, and if no index is specified, POP returns the last item in the list
7.remove (x), removes the first element of the matching object x in the list, produces an exception when the element is matched, returns none
8.reverse (), reverses the order of the list elements
9.sort (), sort the list, return the None,bisect module can be used to add and delete sorted list items
