If your goals are aimed at the Cloud, you can take advantage of Python’s set of logging handlers to redirect content. Logging.basicConfig(level=logging.DEBUG, format= '%(asctime)s - %(levelname)s - %(message)s') This is an example of a basic logger in Python:

The message then propagates up the logger tree until it hits the root logger, or a logger up in the tree that is configured with propagate=False. When you send a message into one of the loggers, the message gets output on all of that logger’s handlers, using a formatter that’s attached to each handler. These multiple logger objects are organized into a tree that represents various parts of your system and different third-party libraries that you have installed. Formatters specify the layout of log records in the final output.Filters provide a finer grained facility for determining which log records to output.Handlers send the log records (created by loggers) to the appropriate destination.Loggers expose the interface that application code directly uses.

The logging library is based on a modular approach and includes categories of components: loggers, handlers, filters, and formatters. The specifications for the logging configuration format are found in the Python standard library. You can also configure Python logging subsystem using an external configuration file. Once the Python JSON logger is configured, it becomes part of the Python interpreter process that is running the code. The Python standard library provides a logging module as a solution to log events from applications and libraries.

In this post, you’ll find out examples of different outputs. Other advantages of logging in Python is its own dedicated library for this purpose, the various outputs where the log records can be directed, such as console, file, rotating file, Syslog, remote server, email, etc., and the large number of extensions and plugins it supports. So, why learn about logging in Python? One of Python’s striking features is its capacity to handle high traffic sites, with an emphasis on code readability.
