关于Python3编译时“no encoding declared“ 报错解决方法

1.在使用Pycharm编译的时候出现如下错误：

 File "C:/Users/pc/PycharmProjects/test/main.py", line 2
SyntaxError: Non-ASCII character '\xe7' in file C:/Users/pc/PycharmProjects/test/main.py on line 2, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

2.问题解决：

#coding=utf-8

或者

# -*- coding:utf-8 -*-
