Python自定义logger模块的实例代码

import logging

# 创建日志记录器
logger = logging.getLogger('码农研究僧')
logger.setLevel(logging.DEBUG)

# 创建处理程序并设置级别
console_handler = logging.StreamHandler()

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

# 将处理程序添加到日志记录器
logger.addHandler(console_handler)

# 记录日志
