Add Logs

Logging is a crucial aspect of any software system, as it allows developers to keep track of what’s happening in their code and quickly diagnose and fix issues when they arise. The logging module in Python provides a powerful and flexible way to manage logging in your application.

Step 1: Import the logging module

Start by importing the logging module in your Python file:

import logging

Step 2: Get a logger instance

To use the logging module, you first need to get an instance of the logger. You can create a logger with a specific name by calling the getLogger() method on the logging module:

db_logger = logging.getLogger('db')

Here, we’re creating a logger with the name ‘db’, which we’ll use to log messages related to our database operations.

Step 3: Log messages

Once you have a logger instance, you can use it to log messages at different levels of severity, including debug, info, warning, error, and critical. Here’s an example of logging an info message:

db_logger.info('info message')

You can also log warning messages:

db_logger.warning('warning message')

Step 4: Log exceptions

In addition to logging messages, you can also log exceptions using the exception() method of the logger. Here’s an example:

try:
    1/0
except Exception as e:
    db_logger.exception(e)

This code will log the exception message and stack trace at the ERROR level.

Step 5: Configure logging settings

By default, the logging module will write log messages to the console. However, you can customize the logging settings by configuring a logging handler. For example, you can write log messages to a file or send them to a remote server. You can also customize the log format and level.
