python開頭的coding設置

緣起：

[root@CentOS7 code]# python multi_thread_mfw.py 
  File "multi_thread_mfw.py", line 138
SyntaxError: Non-ASCII character '\xe5' in file multi_thread_mfw.py on line 138, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

寫完python代碼運行時，報類似SyntaxError: Non-ASCII character ‘\xe5’ in file *.py，
基本可以斷定，python文件開頭未設置coding=utf-8。

#!/usr/bin/python
# coding=utf-8

# TODO: anything

或者：

#!/usr/bin/python
# -*- coding:utf-8 -*-

# TODO: anything

vim語法

vim中對python語法高亮，正則匹配規則：

\%^.*\n.∗\?#.*coding[:=]\s*[0-9A-Za-z-_.]\+.*$
