Python Logging – INFO Level To log an INFO line using Python Logging, Check if the logger has atleast a logging level of INFO. Use logging.info() method, with the message passed as argument, to print the INFO line to the console or log file.
You can configure logging as shown above using the module and class functions or by creating a config file or a dictionary and loading it using fileConfig() or dictConfig() respectively. These are useful in case you want to change your logging configuration in a running application.
Use the logging Module to Print the Log Message to Console in Python. To use logging and set up the basic configuration, we use logging. basicConfig() . Then instead of print() , we call logging.
We can also use the logging. FileHandler() function to write logs to a file in Python. This function takes the file path where we want to write our logs. We can then use the addHandler() function to add this handler to our logger object.
The root logger always defaults to WARNING level. Try calling
logging.getLogger().setLevel(logging.INFO)
and you should be fine.
Like @ztyx said that default logger level is WARNING. You have to set it to a lower level
You can do it by using logging.basicConfig and setting logger level:
logging.basicConfig(level=logging.DEBUG)
The above solutions didn't work for me, but the code here did:
# set up logging to file
logging.basicConfig(level=logging.DEBUG,
format='%(asctime)s %(name)-12s %(levelname)-8s %(message)s',
datefmt='%m-%d %H:%M',
filename='/temp/myapp.log',
filemode='w')
# define a Handler which writes INFO messages or higher to the sys.stderr
console = logging.StreamHandler()
console.setLevel(logging.INFO)
# add the handler to the root logger
logging.getLogger('').addHandler(console)
(I omitted parts of the code for the sake of readability)
This will work
import logging
logging.basicConfig()
logger = logging.getLogger(__name__)
logger.setLevel(logging.INFO)
logger.info('its working')
