[resolved] question about Python not displaying Chinese: syntaxerror:non-ascii character ' \xe4 ' in file test.py on line 3, but no encoding declared.

Want to output Chinese characters in Python code. But always appears syntaxerror:non-ascii character ' \xe4 ' in the file test.py on line, but no encoding declared. (test.py is my own file, the prompt error appears in line 4th, your file will be prompted accordingly). A simple example of the test.py code is as follows:

1 #!/usr/bin/python2 3 print "How are you?"

After executing the python test.py command under the terminal,

File "test.py", line 3

Syntaxerror:non-ascii character ' \xe4 ' in the file test.py on line 3, but no encoding declared; See http://www.python.org/peps/pep-0263.html for details

This is a Python encoding problem, the default encoding format in Python is ASCII format, so the Chinese characters cannot be printed correctly without modifying the encoding format.

Workaround: In each subsequent Python file that needs to display Chinese characters, you can use the following method to define the encoding format in the next line of #!/usr/bin/python, and I use the UTF-8 encoding as an example.

The first type:

1 #!/usr/bin/python2 #coding: utf-83 print "How are you?"

The second type:

1 #!/usr/bin/python2 #-*-coding:utf-8-*-3 print "How are you?"

The third type:

1 #!/usr/bin/python2 #vim: Set fileencoding:utf-83 print "How are you?"

　　* * Special Note: This line of code that defines the encoding format must be placed on the first or second line, typically if the first line is the code that prompts the Python location, then the line defining the encoded format must be placed on the second line, otherwise the error will still be indicated.
