    # Variables (to make the calls that follow work)
    hostname = 'www.python.org'
    item = 'spam'
    filename = 'data.csv'
    mode = 'r'
    
    # Example logging calls (insert into your program)
    logging.critical('Host %s unknown', hostname)
    logging.error("Couldn't find %r", item)
    logging.warning('Feature is deprecated')
    logging.info('Opening file %r, mode = %r', filename, mode)
