In this issue, the editor will bring you about the characteristics of different types of objects in python. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

1. The string has an index, and the elements in the string can be repeated.

Immutable, unmodifiable.

2. The list can be indexed and sliced.

Elements can be modified and are mutable.

3. Tuples can be regarded as lists that cannot be modified.

Elements cannot be modified directly, but can also be indexed and sliced, similar to lists.

4. The dictionary consists of key values, and the key must be a variable data type.

The value can be arbitrary data and the dictionary is out of order.

String property example

S = 'hello'# index: 0 1234 index starts at 0 print (s [0])-- > hprint (s [1])-- > e# take out the last character print (s [4])-- > oprint (s [- 1])-- > start:stop:step [start:stop:step] from satrt to end-1 Step size is stepprint (s [0:3])-- > helprint (s [0: 4:2])-- > hl# displays all characters print (s [:])-- > hello# shows the first three characters print (s [: 3])-- > reverse print of hello# string (s [::-1])-- > olleh# all characters print except the first character (s [1:]) -> hllo these are the characteristics of different types of python objects shared by the editor.
