我找到了一个解决方案:

logger = logging.getLogger('my-logger')
logger.propagate = False
# now if you use logger it will not log to console.

这将防止日志被发送到包含控制台日志的上层记录器。

完全禁用日志记录:

logging.disable(sys.maxint) # Python 2

logging.disable(sys.maxsize) # Python 3

启用日志记录:

logging.disable(logging.NOTSET)

其他答案提供的工作并不能完全解决问题，例如

logging.getLogger().disabled = True

当n大于50时，

logging.disable(n)

第一个解决方案的问题是它只适用于根日志记录器。使用logging.getLogger(__name__)创建的其他记录器不会被此方法禁用。

第二个解决方案确实会影响所有日志。但是它将输出限制在给定级别之上，因此可以通过记录级别大于50的日志来覆盖它。

这可以通过

logging.disable(sys.maxint)

据我所知(在查看源代码后)，这是完全禁用日志记录的唯一方法。

使用上下文管理器-[最简单]

import logging 

class DisableLogger():
    def __enter__(self):
       logging.disable(logging.CRITICAL)
    def __exit__(self, exit_type, exit_value, exit_traceback):
       logging.disable(logging.NOTSET)

使用示例:

with DisableLogger():
    do_something()

如果你需要[更复杂的]细粒度的解决方案，你可以看看AdvancedLogger

AdvancedLogger can be used for fine grained logging temporary modifications

How it works:
Modifications will be enabled when context_manager/decorator starts working and be reverted after

Usage:
AdvancedLogger can be used
- as decorator `@AdvancedLogger()`
- as context manager `with  AdvancedLogger():`

It has three main functions/features:
- disable loggers and it's handlers by using disable_logger= argument
- enable/change loggers and it's handlers by using enable_logger= argument
- disable specific handlers for all loggers, by using  disable_handler= argument

All features they can be used together

AdvancedLogger的用例

# Disable specific logger handler, for example for stripe logger disable console
AdvancedLogger(disable_logger={"stripe": "console"})
AdvancedLogger(disable_logger={"stripe": ["console", "console2"]})

# Enable/Set loggers
# Set level for "stripe" logger to 50
AdvancedLogger(enable_logger={"stripe": 50})
AdvancedLogger(enable_logger={"stripe": {"level": 50, "propagate": True}})

# Adjust already registered handlers
AdvancedLogger(enable_logger={"stripe": {"handlers": "console"}

子类化你想要暂时禁用的处理程序:

class ToggledHandler(logging.StreamHandler):
"""A handler one can turn on and off"""

def __init__(self, args, kwargs):
    super(ToggledHandler, self).__init__(*args, **kwargs)
    self.enabled = True  # enabled by default

def enable(self):
    """enables"""
    self.enabled = True

def disable(self):
    """disables"""
    self.enabled = False

def emit(self, record):
    """emits, if enabled"""
    if self.enabled:
        # this is taken from the super's emit, implement your own
        try:
            msg = self.format(record)
            stream = self.stream
            stream.write(msg)
            stream.write(self.terminator)
            self.flush()
        except Exception:
            self.handleError(record)

通过名称查找处理程序非常简单:

_handler = [x for x in logging.getLogger('').handlers if x.name == your_handler_name]
if len(_handler) == 1:
    _handler = _handler[0]
else:
    raise Exception('Expected one handler but found {}'.format(len(_handler))

一旦发现:

_handler.disable()
doStuff()
_handler.enable()

我不是很了解日志模块，但是我使用它的方式是我通常只希望禁用调试(或信息)消息。您可以使用Handler.setLevel()将日志级别设置为CRITICAL或更高。

此外，您还可以替换sys。Stderr和sys。打开用于写入的文件的标准输出。见http://docs.python.org/library/sys.html # sys.stdout。但我不建议这样做。

您可以更改特定处理程序的调试模式级别，而不是完全禁用它。

因此，如果你有一个情况，你想停止调试模式的控制台，但你仍然需要保持其他级别，如错误。你可以像下面这样做

# create logger
logger = logging.getLogger(__name__)

def enableConsoleDebug (debug = False):
    #Set level to logging.DEBUG to see CRITICAL, ERROR, WARNING, INFO and DEBUG statements
    #Set level to logging.ERROR to see the CRITICAL & ERROR statements only
    logger.setLevel(logging.DEBUG)

    debugLevel = logging.ERROR
    if debug:
        debugLevel = logging.DEBUG

    for handler in logger.handlers:
        if type(handler) is logging.StreamHandler:
            handler.setLevel (debugLevel)
