I'm trying to use dictConfig to configure logging. I keep running into the error that the logging.StreamHandler object is not iterable.
I'm using Python 3.4.3 on a Windows 7 box.
C:\Python34\python.exe 3.4.3 (v3.4.3:9b73f1c3e601, Feb 24 2015, 22:44:40) [MSC v.1600 64 bit (AMD64)]
I want to use the configobj module to create the dictionary from an INI file, but that's not the problem I'm having.
Here is my test code:
#############
import logging, logging.config, logging.handlers
import configobj
# config = configobj.ConfigObj('loggingtest.ini')
# config['version']=eval(config['version'])
config = {
'version': 1,
'level': 'INFO',
'formatters': {'fmt1': {'format': '%(asctime)s: (%(levelname)s) %(message)s',
'datefmt': ''}
},
'loggers': {'root': {'level': 'INFO',
'handlers': 'cfg://handlers.console'},
'file': {'level': 'WARN',
'handlers': 'cfg://handlers.file'}
},
'handlers': {'console': {'class': 'logging.StreamHandler',
'level': 'INFO',
'stream': 'ext://sys.stdout'},
'file': {'class': 'logging.FileHandler',
'level': 'WARN',
'filename': 'test.log'}
},
}
logging.config.dictConfig(config)

When I run it, I get this traceback:
Traceback (most recent call last):
File "C:\Python34\lib\logging\config.py", line 611, in configure

for h in handlers:
TypeError: 'StreamHandler' object is not iterable
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "L:\workspace\MyPython\src\testlog.py", line 27, in <module>
logging.config.dictConfig(config)
File "C:\Python34\lib\logging\config.py", line 789, in dictConfig
dictConfigClass(config).configure()
File "C:\Python34\lib\logging\config.py", line 614, in configure
'%r: %s' % (name, e))
ValueError: Unable to configure logger 'root': 'StreamHandler' object is not iterable
I even tried creating a JSON file to create the dictionary, and got the same error.
Thanks for any help
