PyDev Console not printing logging for all levels

Question

I have average experience with python, btw i just installed eclipse and pydev on top of it. And strangely the behavior of logging module looks weird.

import datetime
import logging

print datetime.date.today()
print logging
logging.info("test")
print logging.info("test2")

--------
OUTPUT::
--------
2012-10-25
<module 'logging' from '/usr/lib/python2.7/logging/__init__.pyc'>
None

Any clue why logging.info din't work ?

btw not sure if this is related, but just after pydev installation import logging itself wasn't working. Then i checked python interpreter setting and logging module wasn't there in forced builtins list (Windows->preference->Pydev->Interpreter(python)->Forced Builtins). So i added that manually to make import logging work. Thanks in advance for any pointers.

Answer 1

Because the default loglevel is WARNING and logging.info() logs at level lower than that. See the explanation here and the docs .

To do what you want you could try this:

logger = logging.getLogger('name_of_your_logger')
logger.setLevel(logging.INFO)
logger.info("Should get logged")

Answer 2

您可以在第一个日志记录语句之前使用setLevel更改默认级别。

logging.getLogger().setLevel(logging.DEBUG)

Answer 3

Try this if want to write into stdout:

import sys
import logging

logger = logging.getLogger()
handler = logging.StreamHandler(sys.stdout)
handler.setLevel(logging.DEBUG)
logger.addHandler(handler)
logger.setLevel(logging.DEBUG)
logger.info('teste')

Output:

teste
