body: <p>How can I parse tags with no value in an ini file with python configparser module?</p>
  
  <p>For example, I have the following ini and I need to parse rb. In some ini files rb has integer values and on some no value at all like the example below. How can I do that with configparser without getting a valueerror? I use the getint function</p>

  id=000
  rb=
  </code></pre>
