How can I create a custom log format in Python?

You can create a custom log format in Python using the logging module. You can define your format using the Formatter class.

Can you show me a code example?

Sure! Here's a simple example:

import logging

# Create a custom logger
logger = logging.getLogger('my_logger')

# Create handlers
handler = logging.StreamHandler()

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

# Set the formatter for the handler
handler.setFormatter(formatter)

# Add the handler to the logger
logger.addHandler(handler)
logger.setLevel(logging.INFO)

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

What do the format specifiers mean?

In the format string:

• %(asctime)s is the time when the log entry was created.
• %(name)s is the name of the logger.
• %(levelname)s is the severity level of the log message.
• %(message)s is the actual log message.
