[Tutor] string-formatted dictionary keys of configparsed INI file

[Eur van Andel]

Hi

I managed to parse an ini file with the configparser thanks to Karl who pointed
me at an example in the cookbook:

http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/65334

I have the values as integers, just as I want, but the dictionary keys are
strings:

>import ConfigParser
>import string
>
>_ConfigDefault = {}
>
>def LoadConfig(file, config={}):
>   """
>   returns a dictionary with key's of the form
>   <section>.<option> and the values 
>   """
>   config = config.copy()
>   cp = ConfigParser.ConfigParser()
>   cp.read(file)
>   for sec in cp.sections():
>      name = sec
>      for opt in cp.options(sec):
>         config[name + "." + opt] = int(cp.get(sec, opt).strip())
modified from example to get int() values. 

>   return config
>
>if __name__=="__main__":
>   cf = LoadConfig("config.ini", _ConfigDefault)
>   print cf
>
>   for n in range(cf['main.number_of_fans']):
>      print cf['fan' + '%1d' % n+'.dtai']

While this does work (ini file is posted below) I would like to address the
values as:

	cf[fan0.dtai]

instead of 

	cf['fan0.dtai']

What did I do wrong?
