python 常见报错 Non-ASCII character '\xe5'

SyntaxError: Non-ASCII character '\xe5' in file D:/pycharm/TEST02/python file/images/ListTest01.py on line 3, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details

此问题导致的原因是头部没有添加 ：
#! user/bin/python
#- * -coding:UTF-8 - * -

#! user/bin/python
#-*- coding: UTF-8 -*-

#创建一个list 列表
L = [1, "hello", True, 1.2]
print(L)  # 打印出L列表
