避免使用logger = logging.getLogger(__ name__)而不丢失过滤日志的方法 [英] Avoid `logger=logging.getLogger(__name__)` without loosing way to filter logs

问题描述

我很懒，并且希望在每个使用日志记录的python文件中避免出现这一行:

I am lazy and want to avoid this line in every python file which uses logging:

logger = logging.getLogger(__name__)

在一月份，我问如何做到这一点，并找到了答案:避免`logger = logging.getLogger(__ name __)`

In january I asked how this could be done, and found an answer: Avoid `logger=logging.getLogger(__name__)`

不幸的是，那里的答案有一个缺点，那就是您失去了过滤功能.

Unfortunately the answer there has the drawback, that you loose the ability to filter.

我真的想避免这条无用和多余的线.

I really want to avoid this useless and redundant line.

示例:

import logging

def my_method(foo):
    logging.info() 

不幸的是，如果第一次在该文件中调用logging.info()，我认为不可能隐式地执行logger = logging.getLogger(__name__).

Unfortunately I think it is impossible do logger = logging.getLogger(__name__) implicitly if logging.info() gets called for the first time in this file.

外面有人知道怎么做不可能的事情吗?

Is there anybody out there who knows how to do impossible stuff?

更新

我喜欢不要重复自己.如果大多数文件的顶部都包含同一行，则我认为这是重复.看起来像是 WET .每当我看到那里时，脑海中的python解释器都需要跳过此行.我的主观感觉:这条线是没用的膨胀.该行应为隐式默认值.

I like Don't Repeat Yourself. If most files contain the same line at the top, I think this is a repetition. It looks like WET. The python interpreter in my head needs to skip this line every time I look there. My subjective feeling: this line is useless bloat. The line should be the implicit default.

推荐答案

我很懒，我想在每个使用 记录:

I am lazy and want to avoid this line in every python file which uses logging:

logger = logging.getLogger(__name__)

好吧，这是推荐的方式:

Well, it's the recommended way:

命名记录器时要使用的一个很好的约定是使用模块级 记录器，在使用日志记录的每个模块中，命名如下:

A good convention to use when naming loggers is to use a module-level logger, in each module which uses logging, named as follows:

logger = logging.getLogger(__name__)

这意味着记录器名称跟踪程序包/模块的层次结构，并且 从直观上很明显，仅从记录器记录事件的位置 名称.

This means that logger names track the package/module hierarchy, and it’s intuitively obvious where events are logged just from the logger name.

这是来自官方 howto 的引用.

That's a quote from the official howto.

它遵循显式优于隐式".无论如何，您可以轻松地在许多IDE中更改python模板，以始终包含此行或创建新的模板文件.

It follows "Explicit is better than implicit". Anyway you can easily change a python template in many IDEs to always include this line or make a new template file.
