解决UnicodeDecodeError: ‘gbk‘ codec can‘t decode byte 0x8c in position : illegal multibyte sequence

• 问题描述：在命令行输入python并回车时，会进入python交互式环境，但是有的时候会出现如下的错误

• 错误原因：python会把在我们在交互式环境下输入的命令，都保存到C:\Users\dedsec\.python_history文件下（可以用命令os.path.expanduser('~/.history')获取该文件路径），每次启动交互式环境就会读取这个文件，使我们能调用历史命令，不过如果输入了中文，则会出现无法读取的问题
• 解决方案：如果不想修改源代码中for line in open(filename, 'r'):的编码格式，可以用记事本打开C:\Users\dedsec\.python_history文件，然后把内容清空，问题解决
