SyntaxError: Non-UTF-8 code starting with '\xd1' in file drawtree.py on line 15, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

遇到如上编码问题：
SyntaxError: Non-UTF-8 code starting with '\xd1' in file drawtree.py on line 15, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details
需要在代码起始部分加上
#coding:utf-8
即可解决问题

如果不行请 尝试
# coding=gbk
