Python日志字典配置

Question

我正在尝试为Python配置一些日志记录。从 http://docs.python.org/howto/logging.html 建议使用YAML配置文件-

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]

在我的代码中，我用这个作为-

^{pr2}$

但是，运行它时，我得到一个错误

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

所以我似乎调用配置文件的方式不正确。只是找不到正确的方法来调用它。请帮忙？ 非常感谢

您需要加载并解析YAML文件：

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