如何为文件配置的python logger设置新的文件名？

import logging
import logging.handlers

logger = logging.getLogger(__name__)

log_file = 'new_log_file.log'
file_handler = logging.handlers.RotatingFileHandler(log_file, maxBytes=1024, backupCount=5)

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

logger.addHandler(file_handler)

import logging
import logging.handlers

logger = logging.getLogger(__name__)

log_file = 'new_log_file.log'
file_handler = logging.handlers.RotatingFileHandler(log_file, maxBytes=1024, backupCount=5)

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

logger.addHandler(file_handler)

# 示例日志输出
logger.info('This is a new log message.')
