3. 每个logging对象打LOG的时候,也会把LOG信息传递到传递到上层logging对象中,对于c->b->a->root这种情况,这个LOG其实会打4次,以c、b、a、root循序依次打一个LOG。 可能有人会问,像我之前一般用A模块或者B模块那样的方式去初始化一个logging对象,这样初始化的对象也会是root logging对象的一个孩子,而root l...
For example, the string "CRITICAL" maps to CRITICAL. The returned mapping is copied from an internal mapping on each call to this function. 3.11 新版功能. logging.getLevelName(level) 返回日志记录级别 level 的字符串表示。 如果level 为预定义的级别 CRITICAL, ERROR, WARNING, INFO 或DEBUG 之一...
Many of the more elaborate log handlers in the logging library can easily block the application, causing outages simply because the logging infrastructure was unresponsive. For these reasons, it is often best to keep the logging configuration of an application as simple as possible. A growing ...
logging.basicConfig(filename='example.log',level=logging.DEBUG) logging.debug('This message should go to the log file') logging.info('So should this') logging.warning('And this, too') 结果就是,产生一个example.log 文件,内容为 DEBUG:root:This message should go to the log file ...
下面的代码将日志输出到文件中：logging.basicConfig(filename='example.log', level=logging.DEBUG)这样...
print(new_system.modern_method()) # 输出: This comes from an old library. (adapted for new system) 通过上述例子和介绍,我们已经初步领略了Python语言的特点和设计模式的重要作用。随着后续章节的深入探讨,我们将看到如何在Python中运用装饰器这一重要设计模式,以实现代码的可重用性和功能性增强。
