SyntaxError: Non-ASCII character '\xe6' in file test.py on line 1, but no encoding declared; see htt

最近敲python 遇到了下面这个错误:

SyntaxError: Non-ASCII character '\xe6' in file test.py on line 1, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

解决办法:

在该.py的文件头部添加: 下列代码,即可!

# -*- coding: utf-8 -*

从#号开始复制, 点击运行,即可解决上述问题

为啥出现该问题的原因:

一、使用中文字符
在python源码中如果使用了中文字符，运行时会有错误，解决的办法是在源码的开头部分加入字符编码的声明，下面是一个例子：
#!/usr/bin/env python
# -*- coding: cp936 -*-
Python Tutorial中指出，python的源文件可以编码ASCII以外的字符集，最好的做法是在#!行后面用一个特殊的注释行来定义字符集：
# -*- coding: encoding -*-
根据这个声明，Python会尝试将文件中的字符编码转为encoding编码，并且，它尽可能的将指定地编码直接写成Unicode文本。
注意，coding:encoding只是告诉Python文件使用了encoding格式的编码，但是编辑器可能会以自己的方式存储.py文件，因此最后文件保存的时候还需要编码中选指定的ecoding才行。
