When working with IPython Notebook, it can be quite distracting to have the logging output displayed with a red background color. This can make it difficult to read and understand the logs. In this article, we will explore three different ways to avoid the red background color for logging output in IPython Notebook.

Option 1: Using the logging module

The first option is to use the logging module in Python. This module provides a flexible framework for emitting log messages from Python programs. By default, the logging module uses the StreamHandler class to output log messages to the console. We can customize the formatting of the log messages to avoid the red background color.

import logging

# Create a logger
logger = logging.getLogger()
logger.setLevel(logging.INFO)

# Create a formatter
formatter = logging.Formatter('%(asctime)s - %(levelname)s - %(message)s')

# Create a handler
handler = logging.StreamHandler()
handler.setFormatter(formatter)

# Add the handler to the logger
logger.addHandler(handler)

# Log a message
logger.info('This is a log message')

By setting the log level to INFO and customizing the formatter, we can avoid the red background color for logging output in IPython Notebook. This option provides a lot of flexibility and control over the logging output.

Option 2: Using IPython’s display module

The second option is to use IPython’s display module, which provides a way to customize the display of objects in IPython Notebook. We can use the display module to override the default behavior of the logging output and avoid the red background color.

from IPython.display import display, HTML

# Override the default behavior of the logging output
def custom_display(obj):
    display(HTML(f"
{obj}
"))
# Redirect the logging output to the custom display function

logger.addHandler(logging.StreamHandler(stream=custom_display))
# Log a message

logger.info('This is a log message')

By redirecting the logging output to a custom display function, we can control how the log messages are displayed in IPython Notebook. This option allows for more customization of the logging output.

Option 3: Using IPython’s magic commands

The third option is to use IPython’s magic commands, which provide a way to control the behavior of IPython Notebook. We can use the %config magic command to customize the logging output and avoid the red background color.

# Customize the logging output
%config Application.log_level = 'INFO'
%config Application.log_format = '%(asctime)s - %(levelname)s - %(message)s'

By using the %config magic command, we can easily customize the logging output in IPython Notebook. This option is the simplest and requires the least amount of code.

After exploring these three options, it is clear that the best option depends on the specific requirements and preferences of the user. Option 1 provides the most flexibility and control over the logging output, but it also requires more code. Option 2 allows for more customization of the logging output, but it may be more complex to implement. Option 3 is the simplest and requires the least amount of code, but it may not provide as much control over the logging output. Ultimately, the best option is the one that meets the user’s needs and preferences.
