计划的 cron Python 脚本日志记录的工作方式与手动运行时不同

Question

I have a Python script that is running as a cron job every day. I'm trying to get it to only output when necessary so that cron doesn't email me unless there is a warning or error. However, DEBUG-level output is still being emailed to me, even though I've set the logging level to WARNING.

import logging
logging.basicConfig(level=logging.WARNING)

When I run the script through IDLE this works as intended with no output. (If I omit those two lines, I get a bunch of DEBUG output). But when the script runs through the cron schedule, I'm being emailed those DEBUG lines.

My crontab is simple:

DISPLAY=:0.0
0 6 * * * python3 /home/pi/script.py

Any ideas?

Answer 1

I figured it out. I was setting the default logging level after importing the module that was automatically generating that debug output. Kind of obvious now.
