title: CGI - FieldStorage - Data from field storage returns a MiniFieldStorage
body: <p>I have an HTML form which returns a submits a single value. The code for which is as below:</p>
  
  <pre><code>&lt;form action="/cgi-bin/filter.cgi" method = "get"&gt;Filter By Version: &lt;input    type="text" name="filter"/&gt;&lt;input type="submit" value="submit"/&gt;&lt;/form&gt;
  </code></pre>
  
  <p>The CGI is as follows:</p>
  
  <pre><code>#!/usr/bin/python
  import cgi
  formData = cgi.FieldStorage()
  </code></pre>
  
  <p>When I print the value of formData. I get the following output:</p>
  
  <p><strong>FieldStorage(None, None, [MiniFieldStorage('filter', '112')])</strong></p>
  
  <p>How can I get the information of "filter"? Why am I getting the value in "MINIFIELDSTORAGE"?</p>
