Here is my code
logger = logging.getLogger("JarvisAI")# Create handlersc_handler = logging.StreamHandler()f_handler = logging.FileHandler(logname)c_handler.setLevel(logging.WARNING)f_handler.setLevel(logging.INFO)# Create formatters and add it to handlersc_format = logging.Formatter('%(name)s - %(levelname)s - %(message)s', "%Y-%m-%d %H:%M:%S")f_format = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s', "%Y-%m-%d %H:%M:%S")c_handler.setFormatter(c_format)f_handler.setFormatter(f_format)# Add handlers to the logginglogger.addHandler(c_handler)logger.addHandler(f_handler)Runninglogger.info("Test") does not produce anything in the logfile.Howeverlogger.warning and other higher log level works fine both in console and file.Pls help.

But a simple search forpython logging no output here on StackOverflow would have been a good thing to do for the OP.9769953– 97699532022-09-04 10:54:12 +00:00CommentedSep 4, 2022 at 10:54

The logger itself also has a logging level, and that needs to be below (or above, depending on your point of view) that of the handlers to show the handlers' output:
logger.setLevel(logging.INFO)(or even debug level: the formatters' levels will prevent debugging info from being output anyway) will do that.
This is also shown in the first code block ofthe Python logging cookbook. Have a read through it.
The reason you are getting warning and higher log level output, is because warning is the default logging level.
