在Python 3中打印日志时添加代码行？

import logging

# 创建logger对象
logger = logging.getLogger(__name__)

# 设置日志级别
logger.setLevel(logging.DEBUG)

# 创建控制台处理器
console_handler = logging.StreamHandler()
console_handler.setLevel(logging.DEBUG)

# 创建格式化器
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')

# 将格式化器添加到处理器
console_handler.setFormatter(formatter)

# 将处理器添加到logger对象
logger.addHandler(console_handler)

# 打印日志
logger.debug("This is a debug message")
logger.info("This is an info message")
logger.warning("This is a warning message")
logger.error("This is an error message")
logger.critical("This is a critical message")
