问题:

Non-ASCII character '\xe5' in file Apriori.py on line 1, but no encoding declared 解决办法

python中出现Non-ASCII character '\xe7' in file ex6.py on line 1, but no encoding declare的错误

可按照错误建议网址查看http://www.python.org/peps/pep-0263.html

发现是因为Python在默认状态下不支持源文件中的编码所致。解决方案有如下三种:

一、在文件头部添加如下注释码:

 # coding=<encoding name> 例如,可添加# coding=utf-8

二、在文件头部添加如下两行注释码:

#!/usr/bin/python

# -*- coding: <encoding name> -*- 例如,可添加# -*- coding: utf-8 -*-

三、在文件头部添加如下两行注释码:

 #!/usr/bin/python

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