logs are also exported to three destinations defined by handler. If you call Logging.getloggeer (' Simpleexample '), the logger instance that matches the name ' Simpleexample ' in the configuration file is created, and its handler is console, which is the output log on the console.Logging.handlers.RotatingFileHandler can implement automatic log file coverage, if you need to implement log file changes (such as deleted) automatically generated, you need to use Logging.handlers.WatchedFileHandler,

logger with a different name, each time it is a new logger, there is no problem adding multiple handler. PS: That's a stupid way to do it, but that's what I did before. ） Call RemoveHandler () to remove the handler from the logger after each log has been recorded as above.

The following is a code example of Method
