Add custom python logging lvlname -

i'm used using log levels using following standard logging methods:

logging.info('info message') logging.debug('debug message')

and have formatter following

stream_formatter = logging.formatter('%(asctime)s - %(levelname)s - % - %(message)s')

so log looks like:

2016-06-01 23:18:42,602 - info - info message 2016-06-01 23:18:42,700 - debug - debug message

i want create new logging level follows:

logging.log(15, 'new level')

how print like:

2016-06-01 23:18:42,800 - custom_level - new level

found in documentation there public method in logging module: logging.addlevelname(lvl, levelname)

custom_level = 15 logging.addlevelname(custom_level, 'custom_level')
