title: Python/Mechanize doesn't recognize input form
body: <p>Newbie here.</p>
  
  <p>I'm trying to mechanize to input text into a search box on a website.</p>
  
  <p>For some reason, it seems like the search box doesn't count as a form.</p>
  
  <p>The "form" looks like this: </p>
  
  <pre><code>&lt;th align="left" scope="col"&gt; 
  &lt;input type="text" name="searchbox" id="searchboxid" size="40" class="search_box ac_input" autocomplete="off"&gt;
  </code></pre>
  
  <p>I get this error message:</p>
  
  <pre><code>select_form
      raise FormNotFoundError("no form matching "+description)
  </code></pre>
  
  <p>My code:</p>
  
  <pre><code>import urllib
  import urllib2
  import cookielib
  import requests
  import mechanize
  from mechanize._opener import urlopen
  from mechanize._form import ParseResponse
  
  browser = mechanize.Browser()
  browser.open("theadress.com")
  
  browser.select_form(nr=0)
  browser.form["searchbox"] = "input"
  browser.submit()
  </code></pre>
  
  <p>I have also tried finding the form by using <code>browser.select_form[name="searchbox"]</code> but get the same error message.</p>
  
  <p>Trying to list the forms yields nothing:</p>
  
  <pre><code>for form in browser.forms():
      print "Form name:", form.name
      print form
  </code></pre>
