推荐答案

这意味着，您应该将代码重写为:

This means, that you should rewrite your code as:

logging.debug("detect mimetypes faild because %s", e)

根据 https://docs.python.org/2/library/logging.html

Logger.debug(msg, *args, **kwargs)

... 在这个记录器上记录一个级别为 DEBUG 的消息.msg 是消息格式字符串，args 是使用字符串格式化操作符合并到 msg 中的参数.(注意这个意味着您可以在格式字符串中使用关键字以及单个字典参数.) ...

... Logs a message with level DEBUG on this logger. The msg is the message format string, and the args are the arguments which are merged into msg using the string formatting operator. (Note that this means that you can use keywords in the format string, together with a single dictionary argument.) ...
