Python has a built-in module logging which allows writing status messages to a file or any other output streams. The file can contain information on which part of the code is executed and what problems have arisen. There are five built-in levels of the log message.

logger = logging.getLogger(__name__) # Logger in python example logger.info("This is an information message") logger.warning("This is a warning message") This example demonstrates the basics of the logging module in python and shows how to use python logger logging in your application. Let's start with a simple logging configuration:

This example demonstrates the basics of the logging module in python and shows how to use python logger logging in your application. Let's start with a simple logging configuration: logging.basicConfig( level=logging.INFO, format='%(asctime)s - %(name)s - %(levelname)s - %(message)s' ) # Your first logger

The key benefit of having the logging API provided by a standard library module is that all Python modules can participate in logging, so your application log can include your own messages integrated with messages from third-party modules. Here’s a simple example of idiomatic usage: If you run myapp.py, you should see this in myapp.log:
