执行python文件报错：
File "E:/Program Files (x86)/PyCharm 2021.1/fmz_zp/Python/基础/test.py", line 531
SyntaxError: Non-UTF-8 code starting with '\xe4' in file E:/Program Files (x86)/PyCharm 2021.1/fmz_zp/Python/基础/test.py on line 531, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details
解决方法：
在文件第一行增加：
# -*- coding: utf-8 -*-
