title: ConfigParser use default with int values
body: <p>I'm trying use <code>ConfigParser</code> with setting of some default values. I know how to set those default values but having trouble with integers.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>import ConfigParser
  
  defaults = {
      "str1": "val1",
      "str2": "val2",
      "int1": 10,
      "int2": 20
     }
  
  section = "some_section"
  
  config = ConfigParser(defaults)
  
  print config.get(section, "str1")
  print config.get(section, "str1")
  print config.getint(section, "int1")
  print config.getint(section, "int2")
  </code></pre>
  
  <p>The default values works fine when some of the string values are not being provided.
  But, when some of the integers values are not provided and the default value need to be used, exception of <code>TypeError: argument of type 'int' is not iterable</code> being thrown</p>
  
  <p>I didn't found any example of integers as default values. Any help?</p>
