What are some advanced logging techniques in Python 3.10?

In Python 3.10, you can use features like structured logging, custom log levels, and asynchronous logging. Would you like to know more about any specific technique?

Can you explain structured logging?

Structured logging involves logging data in a structured format, like JSON, which makes it easier to query and analyze. You can use the json module to format your logs.

How do I implement custom log levels?

You can create custom log levels by subclassing the logging.Logger class and defining your own levels using addLevelName. Would you like a code example?

Yes, please provide a code example for custom log levels.

Here's a simple example:

import logging

class CustomLogger(logging.Logger):
    CUSTOM_LEVEL = 25
    logging.addLevelName(CUSTOM_LEVEL, 'CUSTOM')

    def custom(self, message, *args, **kwargs):
        if self.isEnabledFor(self.CUSTOM_LEVEL):
            self._log(self.CUSTOM_LEVEL, message, args, **kwargs)

logging.setLoggerClass(CustomLogger)
logger = logging.getLogger(__name__)
logger.custom('This is a custom log message!')
