python selenium select one hidden item from dropdown list
<p>I have this xml code with a dropdown box with name "tp" which I sucessfully accessed by name "tp" and click() to pull down a list of options but unable to get into "Today" with value "919" as below</p>

<pre><code>&lt;span id="sp_tp" class="dropdown select-container"&gt;
    &lt;select name="tp" rel="Timeperiod:" id="cc_tp"  onchange=";" data-selenium-id="Timeperiod:"&gt;
        &lt;option data-selenium-id="Timeperiod::925" value="925" title="Last 4 Weeks"&gt;Last 4 Weeks&lt;/option&gt;                              
        &lt;option data-selenium-id="Timeperiod::919" value="919" selected="selected" title="Today"&gt;Today&lt;/option&gt; 
</code></pre>

<p>I tried with name as below but failed. Can you help</p>

<pre><code>select_Timeperiod = driver.find_element_by_name('tp')
select_Timeperiod.click()
select_Timeperiod.find_element_by_name('Today').click()
</code></pre>

<p>I also tried xpath and id also failed.</p>
