1) Problem Description

When writing Python code, it is useful to output Chinese characters, but the above error is found after running.

(2) Problem Solving

After learning the connection given in the error code, it is found that it is an encoding problem. If there are non-ASCII characters in python, you must declare the character format at the beginning of the Code. There are three methods to declare characters:

 
 

Select one of the three types, and add the specified encoding format at the beginning of the Code. It will solve the problem just now.

For example, I added:

[Python]
#! /Usr/bin/python
#-*-Coding: UTF-8 -*-

#! /Usr/bin/python
#-*-Coding: UTF-8-*-This solves the problem of displaying Chinese characters.
