The process of using the Python logging framework to record an exception with traceback at the warning or info level involves the following steps:

  1. Import the logging module: First, you need to import the logging module in your Python script.
import logging
  1. Configure the logging module: You need to configure the logging module to define the log output format, log level, and log destination. For example, you can define a basic configuration that logs messages with a level of WARNING or higher to the console.
logging.basicConfig(level=logging.WARNING,
                    format='%(asctime)s - %(levelname)s - %(message)s')
  1. Catch the exception: You need to catch the exception you want to log using the try-except block.
try:
   # Code that may raise an exception
except Exception as e:
   # Handle the exception
  1. Log the exception: Finally, you need to log the exception using the logging.exception() or logging.error() method, which automatically adds the traceback to the log.
logging.warning("An exception occurred", exc_info=True)

The exc_info=True parameter tells the logging framework to include the traceback in the log output. You can replace warning() with any other logging level method you require, such as info() or error().
