python文件編碼格式設置

報錯：

File "./001hellopython.py", line 1
SyntaxError: Non-ASCII character '\xe4' in file ./001hellopython.py on line 1, but no encoding declared;
see http://www.python.org/peps/pep-0263.html for details

原因：

Python默認是以ASCII作為編碼方式的，需要在文件開頭設置一下編碼

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