title: How to configure all loggers in an application
body: <p>Python's logging module lets modules or classes define their own loggers. And different loggers can have different handlers. Some of them may choose to log to a file, while some choose to log to, say, stdout.</p>
  
  <p>Now my application uses several of these modules, each with their own loggers that have various handlers. Can I unify the logging behavior so that all logs go to a log file that I specified? In other words, is there a way to .config() all the loggers' handlers at once, from a single place?</p>
