Python Data Type-List VI

This is the content of the December plan, beginning in January 2018 ~

If there is any mistake, please ask for it ~

A list is the most commonly used Python data type and can appear as a comma-separated value within a square bracket.

The list of data items does not need to have the same type, which is already handy.

To access the available subscript and slice methods

1 list=['a','b','C', 2print(list[0])3print(List[1:4])

a['b'c', 1]

Update, change directly, add element at the end. Append

1 list=['a','b','c' , to]2print(list[0])3 list[0]=14  Print(list[0])

1 list=['a','b','C', 2 list.append (6)3print(list[5])

Del statement to delete the elements of the list

1 list=['a','b','C', 2del list[2]3print(List)

Python Expressions	Results	Description
Len ([1, 2, 3])	3	Length
[1, 2, 3] + [4, 5, 6]	[1, 2, 3, 4, 5, 6]	Combination
[' hi! '] * 4	[' hi! ', ' hi! ', ' hi! ', ' hi! ']	Repeat
3 in [1, 2, 3]	True	Whether the element exists in the list
For x in [1, 2, 3]: print (x, end= "")	1 2 3	Iteration

In addition, its nesting and built-in functions are quite a lot of, later said
