Python对象实例可以同时具有不同的记录器级别吗？

Question

我希望程序中的不同对象具有不同的日志记录级别。这有可能吗？

我创建了一个基类，如下所示，其中包含设置日志记录级别的方法。

class Logging():
""" Utility class for common methods."""

logging_levels = ['DEBUG','INFO']#,'WARNING','ERROR'

@property
def verbosity(self):
    return self.__verbosity

@verbosity.setter
def verbosity(self,verbosity):
    """Method to set verbosity of logging on terminal. Different classes may have different levels of verbosity."""

    assert verbosity in self.logging_levels, '{} is not a valid logging level!'.format(verbosity)

    self.__verbosity = verbosity

    #Set logging level - {DEBUG,INFO,WARNING,ERROR}
    if verbosity == 'DEBUG':
        logging.getLogger().setLevel(logging.DEBUG)

    elif verbosity == 'INFO':
        logging.getLogger().setLevel(logging.INFO)

    elif verbosity == 'WARNING':
        logging.getLogger().setLevel(logging.INFO)

    print('{}:Logging level is set to:{}'.format(self.name,verbosity))

    return self.__verbosity

我的另外两个类继承了“Logging”类，在它们各自的init方法中有以下内容：

self.verbosity = verbosity

但是，我观察到的是，每当使用任何一个类的实例来设置日志级别时，日志级别都是全局设置的。是否有任何方法将日志记录级别限制为特定的类实例？

编辑:利用约翰·戈登的建议，我想出了一个解决方案。请看下面的内容。

我能够通过对Logger类进行以下更改来解决这个问题。

class Logging():
""" Utility class for common methods."""

logging_levels = ['DEBUG','INFO']#,'WARNING','ERROR'


def initialize_logger(self):
    """Initialize loggers for different classes."""

    self.logger = logging.getLogger(type(self).__name__)

@property
def verbosity(self):
    return self.__verbosity

@verbosity.setter
def verbosity(self,verbosity):
    """Method to set verbosity of logging on terminal. Different classes may have different levels of verbosity."""

    assert verbosity in self.logging_levels, '{} is not a valid logging level!'.format(verbosity)

    self.__verbosity = verbosity

    #Set logging level - {DEBUG,INFO,WARNING,ERROR}
    if verbosity == 'DEBUG':
        self.logger.setLevel(logging.DEBUG)

    elif verbosity == 'INFO':
        self.logger.setLevel(logging.INFO)

    elif verbosity == 'WARNING':
        self.logger.setLevel(logging.WARNING)

    self.logger.debug('{}:Logging level is set to:{}'.format(self.name,verbosity))

    return self.__verbosity

我添加了initialize_logger()方法，并在我想要记录的类的init函数中调用它。

self.initialize_logger()
#Set logging level - {DEBUG,INFO,WARNING,ERROR}
self.verbosity = verbosity

最后，我使用了我用logger创建的initialize_logger()对象，而不是logging.debug()。

self.logger.debug('My log message')

现在，我可以单独控制所有类的日志记录级别。
