问题描述
目标:防止时间表每次运行时记录日志.
Objective: prevent schedule from logging every time it runs.
背景:
我正在python项目中使用 logging 和 schedule 库.
I am using the logging and schedule libraries in a python project.
我的日志文件包含有关Raspberry Pi运行的仪器的物理状态的信息，并且每10秒更新一次.
My log file contains information about the physical state of a instrument run by a Raspberry Pi, and is updated every 10 seconds.
我使用 schedule 库来安排定期日志.
I use the schedule library to schedule that periodic log.
此处是我发现的关于 schedule 的有限文档.
Here is the limited documentation I have found for schedule.
问题:
时间表库在每次运行作业时记录该语句.
The schedule library logs this statement, every time it runs a job.
2016-06-29 09:01:51,022 INFO: Running job every 10 seconds do update_log() (Last run...
计划时间表调用的函数是 update_log()，该函数计算每十秒钟运行一次的日志中包含的变量并将其记录下来(下面的示例).
The function that schedule calls is update_log(), a function that calculates the variables included in the log I run every ten seconds and logs them (example below).
2016-06-29 09:01:51,022 INFO: Dist: 12.3 m Rate: 23.8 cm/s
因为 schedule 正在生成它自己的(相当无用的)日志行，这使得我实际上尝试做的日志很难阅读.
Because schedule is producing its own (fairly useless) log line, it makes the logging I am actually trying to do very difficult to read.
目标:
防止记录第一条语句的时间表.
Prevent schedule from logging that first statement.
推荐答案
schedule 模块是专门使用称为 schedule 的记录器.您可以使用 logging 库禁用将此记录器写入主记录器.
import logging
logging.getLogger('schedule').propagate = False
如果您根本不想使用 schedule 的日志，也可以通过将其日志级别设置为高于任何实际日志级别来禁用它.
If you don't want schedule's logs at all, you can also disable it by settings its log level above any real log level.
import logging
logging.getLogger('schedule').setLevel(logging.CRITICAL + 10)
如果您只希望某些消息通过，请将级别设置为常规的 logging 级别.
If you just want some messages to get through, set the level to a regular logging level.
从python2.7开始，您还可以使用 NullHandler .
Since python2.7, you can also use a NullHandler instead.
import logging
logging.getLogger('schedule').propagate = False
logging.getLogger('schedule').addHandler(logging.NullHandler())
