python 运行时报错误SyntaxError: Non-ASCII character '\xe5' in file 1.py on line 2

File "1.py", line 2
SyntaxError: Non-ASCII character ‘\xe5‘ in file 1.py on line 2, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details

原因是：Python默认是以ASCII作为编码方式的，需要在文件开头设置一下编码

# -*- coding: UTF-8 -*-     
或者 
#coding=utf-8
