python中文报错

当输出中文时，错误信息如下：

SyntaxError at /time/

Non-ASCII character 'xe7' in file e:pythonCodefirstsitefirstsiteview.py on line 15, but no encoding declared; see http://www.python.org/peps/pep-0263.html for 

经百度，必须在代码前面加注这两句

#coding=gbk

#coding=utf-8

才解决

from django.http import HttpResponse
#coding=gbk

#coding=utf-8
import datetime
