How to disable logging on the standard error stream in Python?

I found a solution for this:

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

This will prevent logging from being send to the upper logger that includes the console logging.

I use:

logger = logging.getLogger()
logger.disabled = True
... whatever you want ...
logger.disabled = False

You can use:

logging.basicConfig(level=your_level)

where your_level is one of those:

'debug': logging.DEBUG,
'info': logging.INFO,
'warning': logging.WARNING,
'error': logging.ERROR,
'critical': logging.CRITICAL

So, if you set your_level to logging.CRITICAL, you will get only critical messages sent by:

logging.critical('This is a critical error message')

Setting your_level to logging.DEBUG will show all levels of logging.

For more details, please take a look at logging examples.

In the same manner to change level for each Handler use Handler.setLevel() function.

import logging
import logging.handlers

LOG_FILENAME = '/tmp/logging_rotatingfile_example.out'

# Set up a specific logger with our desired output level
my_logger = logging.getLogger('MyLogger')
my_logger.setLevel(logging.DEBUG)

# Add the log message handler to the logger
handler = logging.handlers.RotatingFileHandler(
          LOG_FILENAME, maxBytes=20, backupCount=5)

handler.setLevel(logging.CRITICAL)

my_logger.addHandler(handler)
