How can I format logs in my application?

You can format logs by using structured logging, which allows you to include key-value pairs for better readability.

What are some common log formats I should consider?

Common log formats include JSON, XML, and plain text. JSON is popular for its structure and ease of parsing.

How do I implement JSON logging in Python?

You can use the json module along with the logging library. Set up a custom formatter to output logs in JSON format.

Can you show me a code example?

Sure! Here's a simple example:

import logging
import json

class JsonFormatter(logging.Formatter):
    def format(self, record):
        log_obj = {"level": record.levelname, "message": record.msg}
        return json.dumps(log_obj)

logger = logging.getLogger()
handler = logging.StreamHandler()
handler.setFormatter(JsonFormatter())
logger.addHandler(handler)
logger.setLevel(logging.INFO)
logger.info('This is a log message')
