logging is a crucial aspect of software development, aiding in debugging, monitoring, and understanding the behavior of an application. python's built-in logging module provides a flexible and powerful framework for logging messages.
one important feature of python's logging module is the ability to customize the format of log messages. this tutorial will guide you through understanding and customizing the logging message format in python.
before we dive into customizing the logging message format, let's cover some basic concepts of python logging:
loggers: entry point of the logging system. used to create log records.
handlers: specify where the log records should be output (e.g., console, file).

log levels: indicate the severity of the log message (e.g., debug, info, warning, error, critical).
you can customize the format by adjusting the string passed to the formatter constructor. additionally, you can include other attributes such as module name (%(module)s), function name (%(funcname)s), and line number (%(lineno)d), among others.
customizing the logging message format in python allows developers to tailor log messages to suit their specific needs. by following the steps outlined in this tutorial, you can effectively configure python's logging module to generate log messages with the desired format and content. this flexibility is essential for debugging, monitoring, and analyzing the behavior of python applications.
