Non-ASCII character ‘\xe5‘ in file kf1.py on line 4, but no encoding declared； see http://python.or

PYTHON运行中出现的问题：

SyntaxError: Non-ASCII character '\xe5' in file kf1.py on line 4, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

$Non-ASCII character ‘\xe5‘ in file kf1.py on line 4, but no encoding declared； see http://python.or$

出现的原因：发现是因为Python在默认状态下不支持源文件中的编码所致

解决办法：在文件头部添加如**释码：

# coding=utf-8

还可以添加如下：

#!/usr/bin/python

# vim: set fileencoding=<encoding name> : 例如，可添加# vim: set fileencoding=utf-8 :
