Python logging dictionary config

I am trying to configure some logging for Python. From http://docs.python.org/howto/logging.html It is recommended that we use a YAML configuration file -

version: 1
formatters:
  simple:
    format: '%(asctime)s - %(name)s - %(levelname)s - %(message)s'
handlers:
  console:
    class: logging.StreamHandler
    level: DEBUG
    formatter: simple
    stream: ext://sys.stdout
loggers:
  simpleExample:
    level: DEBUG
    handlers: [console]
    propagate: no
root:
  level: DEBUG
  handlers: [console]

In my code, I use this as -

import logging.config

logging.config.dictConfig('logging.config')

However, on running it, I get an error

Traceback (most recent call last):
  File "TestLogger.py", line 62, in <module>
    Test5()  
  File "TestLogger.py", line 55, in Test5
    logging.config.dictConfig('logging.dict.2.config') 
  File "/usr/lib/python2.7/logging/config.py", line 776, in dictConfig
    dictConfigClass(config).configure()
  File "/usr/lib/python2.7/logging/config.py", line 380, in __init__
    self.config = ConvertingDict(config)
ValueError: dictionary update sequence element #0 has length 1; 2 is required

So it seems that I am invoking the config file in an incorrect way. Just can't find the right way to invoke it. Help please? Thanks so much

You need to load and parse the YAML file:

import yaml
logging.config.dictConfig(yaml.load(open('logging.config', 'r')))
