SyntaxError: Non-UTF-8 code starting with ‘xe8‘ in file解决方法

当文件出现

  File "E:/git_python/git_py/无用文件/222.py", line 2
SyntaxError: Non-UTF-8 code starting with 'xe8' in file E:/git_python/git_py/无用文件/222.py on line 2, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

可通过在文件首处加

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

解决
