Python uses Chinese comments and outputs Chinese (original)

Just started to learn python, need to annotate Chinese in Python and output Chinese, now try;

Only for preliminary study reference, Master please detour.

-----------------------------------------------------------------------

First step: Enter the following command in the code to execute:

#在Python中显示中文注释和输出中文
A = "Chinese"
Print a

Return Error:

D:\Python27\python.exe "D:\test\ Chinese. Py"
Process started >>>
File "D:\test\ Chinese. Py", line 1
Syntaxerror:non-ascii character ' \xe5 ' in file D:\test\ Chinese. Py on line 1, but no encoding declared; See http://python.org/dev/peps/pep-0263/for details
<<< Process finished. (Exit code 1)
================ Ready ================

In the second step, add the encoding format:

#-*-coding:utf-8–*-

#在Python中显示中文注释和输出中文
A = "Chinese"
Print a

return Result:

D:\Python27\python.exe "D:\test\ Chinese. Py"
Process started >>>
Juan Po
<<< Process finished. (Exit code 0)
================ Ready ================

The program can execute correctly, but the output is still garbled.

The third step, find garbled and processing:

Reason: This is because of win, command line with cp936 encoding, and the above script with Utf-8 encoding, resulting in garbled.

The workaround is to re-decode and encode the characters using the decode and encode functions.

#-*-coding:utf-8–*-
#在Python中显示中文注释和输出中文
A = "Chinese"
Print A.decode (' utf-8 '). Encode (' cp936 ')

return Result:

D:\Python27\python.exe "D:\test\ Chinese. Py"
Process started >>>
Chinese
<<< Process finished. (Exit code 0)
================ Ready ================
