如何使用具有多个处理程序的Python日志记录模块将一条日志记录发送到文件，并将另一条日志记录发送到电子邮件

import logging

logger = logging.getLogger('my_logger')
logger.setLevel(logging.DEBUG)

file_handler = logging.FileHandler('log.txt')
file_handler.setLevel(logging.INFO)

email_handler = logging.handlers.SMTPHandler(
    mailhost='smtp.example.com',
    fromaddr='sender@example.com',
    toaddrs=['recipient@example.com'],
    subject='Error Log'
)
email_handler.setLevel(logging.ERROR)

formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
file_handler.setFormatter(formatter)
email_handler.setFormatter(formatter)

logger.addHandler(file_handler)
logger.addHandler(email_handler)

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')
