Easier way to enable verbose logging

Question

I want to add a debug print statement test, if I enable --verbose from the command line and if I have the following in the script.

logger.info(\         


        

Answer 1

Another variant would be to count the number of -v and use the count as an index to the a list with the actual levels from logging:

import argparse
import logging

parser = argparse.ArgumentParser()
parser.add_argument('-v', '--verbose', action='count', default=0)
args = parser.parse_args()

levels = [logging.WARNING, logging.INFO, logging.DEBUG]
level = levels[min(len(levels)-1,args.verbose)]  # capped to number of levels

logging.basicConfig(level=level,
                    format="%(asctime)s %(levelname)s %(message)s")

logging.debug("a debug message")
logging.info("a info message")
logging.warning("a warning message")

This works for -vvvv, -vvv, -vv, -v, -v -v , etc, If no -v then logging.WARNING is selected if more -v are provided it will step to INFO and DEBUG
