[Python] How to add a custom loglevel to Python's logging facility

I'd like to have loglevel TRACE (5) for my application, as I don't think that debug() is sufficient. Additionally log(5, msg) isn't what I want. How can I add a custom loglevel to a Python logger?

I've a mylogger.py with the following content:

import logging

@property
def log(obj):
myLogger = logging.getLogger(obj.__class__.__name__)
return myLogger


In my code I use it in the following way:

class ExampleClass(object):
from mylogger import log

def __init__(self):
'''The constructor with the logger'''
self.log.debug("Init runs")


Now I'd like to call self.log.trace("foo bar")
