I'm working on a small python project that has the following structure -
project -- logs -- project __init.py__ classA.py classB.py utils.py -- main.py I've set up the logging configuration in __init.py__ under project as follows:
import logging from logging import StreamHandler from logging.handlers import RotatingFileHandler # Create the Logger logger = logging.getLogger(__name__) logger.setLevel(logging.INFO) # Create the Handler for logging data to a file logger_handler = RotatingFileHandler('logs\\mylog.log', maxBytes=1024, backupCount=5) logger_handler.setLevel(logging.INFO) #Create the Handler for logging data to console. console_handler = StreamHandler() console_handler.setLevel(logging.INFO) # Create a Formatter for formatting the log messages logger_formatter = logging.Formatter('%(name)s - %(levelname)s - %(message)s') # Add the Formatter to the Handler logger_handler.setFormatter(logger_formatter) console_handler.setFormatter(logger_formatter) # Add the Handler to the Logger logger.addHandler(logger_handler) logger.addHandler(console_handler) Setting up things this way seems to set up the root logger at the package level, and not at the entire project level. As a result, logged statements inside main.py don't appear in the log file, whereas all log statements in the two classes classA and classB as well as utils.py are routed to the console and the log file as expected.
How do I set up the logging so that I'm able to configure it once and use it across the project? I tried moving the logging configuration statements to main.py, but it didn't seem to work.
def setupLogging(): # Create the Logger logger = logging.getLogger(__name__) logger.setLevel(logging.INFO) ..etc.. def main(): setupLogging() if __name__ == "__main__": main()
