Python logging模块打印日志

logging打印日志，文件名为log_config.py

import logging
import sysdef setup_logger(log_file, error_log_file):# 创建一个日志记录器logger = logging.getLogger(__name__)logger.setLevel(logging.DEBUG)  # 设置全局日志级别为 DEBUG# 创建一个文件处理器，将日志写入文件file_handler = logging.FileHandler(log_file)file_handler.setLevel(logging.DEBUG)  # 设置文件日志级别为 DEBUG# 创建一个错误文件处理器，将错误日志单独写入文件error_file_handler = logging.FileHandler(error_log_file)error_file_handler.setLevel(logging.ERROR)  # 设置错误文件日志级别为 ERROR# 创建一个控制台处理器，将日志输出到控制台console_handler = logging.StreamHandler(sys.stdout)console_handler.setLevel(logging.DEBUG)  # 设置控制台日志级别为 DEBUG# 创建一个日志格式化对象formatter = logging.Formatter('%(asctime)s - %(levelname)s - %(message)s')# 将格式化应用到处理器file_handler.setFormatter(formatter)error_file_handler.setFormatter(formatter)console_handler.setFormatter(formatter)# 将处理器添加到日志记录器logger.addHandler(file_handler)logger.addHandler(error_file_handler)  # 将错误文件处理器添加到日志记录器logger.addHandler(console_handler)return loggerif __name__ == '__main__':logger = setup_logger('mail.log', 'error_mail.log')logger.debug('This is a debug message')logger.info('This is an info message')logger.DEBUGing('This is a DEBUGing message')logger.error('This is an error message')logger.critical('This is a critical message')

邮件发送，导入log_config.py配置

import smtplib
import socket
import log_config         #导入log_config.py
