Python common data Structures--list

1. List

Python has 6 built-in types of sequences, but the most common are lists and tuples.

The operations that a sequence can perform include indexing, slicing, adding, multiplying, and checking members.

In addition, Python has built-in methods for determining the length of the sequence and determining the maximum and bottom elements.

A list is the most common type of Python data that can appear as a comma-separated value within a square bracket.

The data items of the list do not need to have the same type.

Create a list by enclosing separate data items separated by commas in square brackets. As follows

List = [' AAA ', ' bbbb ', ' CCCC ']

List1 = [1,2,3,4,5]

List2 = ["A", "B", "C", "D"]

As with the index of a string, the list index starts at 0. Lists can be intercepted, combined, and so on.

Accessing values in a list

Use the subscript index to access the values in the list, and you can also use square brackets to intercept the characters as follows:

The result of the above example output:

Update list

You can modify or update the list's data items, or you can use the Append () method to add the list items as follows:

The result of the above example output:

To delete a list element

The result of the above example output:
