How to use

Using the module is straightforward. Simply import it into your code and instantiate a Logger object which you can then use throughout your code.

# Import f451 Labs Logger
from f451_logger.logger import Logger

# This is optional, but useful if you want to 
# use predefined constant for logging levels
import logging

# Instantiate using defaults ...
myLogger = Logger()

# ... or with custom log level and log file values
myLogger = Logger(

# Call 'log_xxxx' methods to log messages
myLogger.log_info("Hello world!")
myLogger.log_error("Oops! Something broke :-(")

# Call 'debug' method to show message in console
myLogger.debug("Hello world!")
