Logging at the WARNING level?

'Log "The French have the Grail" as a WARNING level message.'

import logging

logging.basicConfig(filename='cc.log', level=logging.DEBUG)

# Write your code below here

logging.debug("ello")

logging.debug("The French Have the Grail", level = logging.WARNING)

Where can I improve my code?

logging.debug("ello")

The above logs an error as debug.

logging.error("this is an error")

The one above this logs the string "this is an error" as an error. Catch the difference? :)

Thank you, after I did that (and corrected a capitalization error in the string) it passed haha

Logging has built-in functions for the various levels:

# Set up logging
logging.basicConfig(filename='cc.log', level=logging.DEBUG)
# output messages
logging.debug('This is a debug message')
logging.info('This is an info message')
logging.warning('This is a warning message')
logging.error('This is an error message')
logging.critical('This is a critical error message')

The "level" says what messages are exposed. Since logging.WARNING > logging.DEBUG (literally!) when level is set to DEBUG all warning messages produced by logging.warning() will be visible. If the level is changed to WARNING, then logging.debug() will not show up and neither would logging.info() mesages.

logging.WARNING, logging.DEBUG, etc. are have integer values so logging.WARNING (30) is literally greater than logging.INFO (20) and logging.DEBUG (10). You can define your own levels

Hi Sayan,

There's no need for the parenthesis on the 2nd line of your code. Also make sure to place each log call on it's own line.

PS You'll get faster feedback and better visibility on your post if you make your own post instead of replying to one that's pretty old like this one.

Also click the 'Markdown Cheatsheet' below your text window when typing your forum post. It will tell you how to make your code show up in a code window. Makes it much easier to diagnose issues with your code.
