title: Transform a python dict into string compatible with Content-Type:"application/x-www-form-urlencoded"
body: <p>I'd like to take a python dict object and transform it into its equivalent string if it were to be submitted as html form data.</p>
  
  <p>The dict looks like this:</p>
  
  <pre><code>{
     'v_1_name':'v_1_value'
    ,'v_2_name':'v_2_value'
  }
  </code></pre>
  
  <p>I believe the form string should look something like this:</p>
  
  <pre><code>v_1_name=v_1_value&amp;v_2_name=v_2_value
  </code></pre>
  
  <p>What is a good way to do this?</p>
  
  <p>Thanks!</p>
