Python日志记录过滤器级别到流

Python Logging Filter Levels to Streams

我正在为我的包设置一个记录器。

我有一个简单的模块，它只启动某些日志处理程序和格式。

文件处理程序
控制台处理程序(拆分为stderr和stdout)
我还设置了一些格式和过滤器。我的过滤器有问题。
我想要有两个处理程序，一个过滤掉信息和调试消息(对于stderr流)，另一个过滤掉警告和以上(留下信息和调试)

我不确定我是否正确设置了筛选类。我得到的这个错误对我来说不是很清楚：

1	TypeError: unbound method filter() must be called with STDErrFilter instance as first argument (got LogRecord instance instead)

这是我的密码，提前谢谢！：

logging.shutdown(info['handlers'])

我想到了，愚蠢的错误。当我添加过滤器而不是传递实例化的对象时，我需要在代码中实例化类。
