除了使用 logging 模块中的 basicConfig 方法配置日志, Python 的 logging.config 模块中, dictConfig 和 fileConfig 方法分别支持通过字典和文件的方式配置 Logger、Handler 和 Formatter。下面用一个例子来简单地说明如何使用文件配置日志,更多详细的用法参考:https://docs.python.org/2/library/logging.config.html

import logging
import logging.config logging.config.fileConfig("logging.conf")
log1 = logging.getLogger("log1") log1.debug('This is a debug message')
log1.info('This is an info message')
