You could either use

logging.debug('ATTEMPTS:%s', attempts)

or

logging.debug('ATTEMPTS:{0}'.format(attempts))

The first method passes two parameters into the logging.debug function which will automatically format the log. The second method passes in a single pre-formatted string into the logging.debug function.

You're formatting the string incorrectly, try:

logging.debug('ATTEMPTS:{0}'.format(attempts))
