Logging is an essential part of software development, providing a way to record information about the execution of a program. Python's built-in logging module makes it easy to incorporate logging into your applications. This tutorial will guide you through the process of setting up a simple logging system with a custom logging format using Python.
The first step is to import the logging module in your Python script or application.
Configure the logging system with the desired settings. This includes setting the logging level, specifying the output handler, and defining the logging format.
In the example above, the logging level is set to DEBUG, and the logging format is defined with three placeholders:
Create a logger instance using the getLogger method. This logger will be used to emit log messages.
Replace _name_ with the name of your module or application.
Now that the logger is set up, you can use it to log messages throughout your code.
Save your script and run it. You should see log messages printed to the console with the specified format.
Feel free to customize the logging format and level according to your needs. The logging module offers a wide range of options for customization.
This tutorial provides a basic example of Python logging with a custom format. As your application grows, you may explore additional features of the logging module, such as log handlers, filters, and loggers hierarchy, to build a robust and flexible logging system.

Logging is a crucial aspect of software development, providing insights into the execution flow, errors, and other relevant information. Python's built-in logging module offers a flexible and powerful logging system. In this tutorial, we'll explore the logging module and dive into formatting options to customize log messages.
Let's start by setting up a basic logging configuration in a Python script:
In this example, we've configured the logging to display messages with a severity level of DEBUG or higher. Adjust the basicConfig function's level parameter to control the verbosity of logged messages.
Customizing the log message format is useful for enhancing readability and including relevant information. The basicConfig function supports a format parameter, allowing you to define a custom format string. Let's modify our script:
In this example, we've added a custom format string using placeholders like %(asctime)s, %(levelname)s, and %(message)s. The datefmt parameter specifies the format for the tim
