Introduction to isb-logger

In this blog post, we’ll explore isb-logger, a powerful and versatile logging library for Python developers. Logging is essential for debugging and monitoring applications, and isb-logger provides a comprehensive set of features to make logging easy and effective.

Getting Started

To start using isb-logger, you first need to install it:

 pip install isb-logger 

Basic Configuration

Here’s a simple example of how to configure isb-logger:

  import isb_logger as logger
logger.setup_logger('example_logger', level='INFO') log = logger.get_logger('example_logger')
log.info('This is an info message') log.warning('This is a warning message') log.error('This is an error message')  

Advanced Configuration

isb-logger supports advanced configurations such as formatting and output file configuration:

  import isb_logger as logger
config = {
  'version': 1,
  'formatters': {
    'simple': {
      'format': '%(asctime)s - %(name)s - %(levelname)s - %(message)s'
    }
  },
  'handlers': {
    'console': {
      'class': 'logging.StreamHandler',
      'formatter': 'simple'
    },
    'file': {
      'class': 'logging.FileHandler',
      'filename': 'app.log',
      'formatter': 'simple'
    }
  },
  'loggers': {
    'example_logger': {
      'handlers': ['console', 'file'],
      'level': 'DEBUG'
    }
  }
}
logger.setup_from_dict(config) log = logger.get_logger('example_logger')
log.debug('This is a debug message') log.info('This is an info message') log.warning('This is a warning message') log.error('This is an error message') log.critical('This is a critical message')  

API Examples

isb-logger comes with a wide range of API functions to provide thorough logging capabilities. Below are some useful API examples:

Custom Levels

  log.log(25, 'This is a custom log level message')  

Logging Exceptions

  try:
  1 / 0
except ZeroDivisionError:
  log.exception('An exception occurred')
 

Contexts

  with logger.log_section(log, 'Important section'):
  log.info('Inside the important section')
 

Example Application

Let’s integrate what we’ve learned into a simple application:

  import isb_logger as logger
def main():
  logger.setup_logger('example_app', level='INFO')
  log = logger.get_logger('example_app')
  
  log.info('Starting the application')

  try:
    result = 10 / 0
  except ZeroDivisionError:
    log.exception('An error occurred')
  
  log.info('Ending the application')

if __name__ == '__main__':
  main()
 

In this example, we configured the logger, started the logging, and handled an exception properly by logging the error details.

By mastering isb-logger, you can efficiently log messages of various severity levels and handle exceptions gracefully in your Python applications.
