Logging using Python’s logging module

In Python, logging is an important technology used to record the running status, errors and other key information of the program. Python's logging module provides a flexible and powerful framework for convenient logging and management. This article will introduce how to use the logging module for logging.

First, we need to import the logging module:

import logging

Next, we can configure the logger. The logging module provides multiple logging levels, including DEBUG, INFO, WARNING, ERROR, and CRITICAL. We can choose the appropriate level according to our needs.

logging.basicConfig(level=logging.DEBUG, format='%(asctime)s - %(levelname)s - %(message)s')

The above code sets the logging level to DEBUG and defines the logging format. %(asctime)sThe time used to represent the log record is used here .%
