    <p>I'm writing a script to collect weather data from a webpage. My code goes as follows:</p> <pre><code>import urllib.request from bs4 import BeautifulSoup # open the webpage and assign the content to a new variable base = urllib.request.urlopen('http://www.weather.com/weather/today/Washington+DC+20006:4:US') f = base.readlines() f = str(f) soup = BeautifulSoup(f) rn_base = soup.find(itemprop="temperature-fahrenheit") right_now = rn_base.string print(right_now) fl_base = soup.find(itemprop="feels-like-temperature-fahrenheit") feels_like = fl_base.string print(feels_like) td_base = soup.find_all('class_="wx-temperature"') print(td_base) </code></pre> <p>So <code>right_now</code> and <code>feels_like</code> print fine, but when it comes to <code>td_base</code>, it returns either <code>None</code> or <code>[]</code>, an empty list depending on whether using <code>.find</code> or <code>.find_all</code>. To paraphrase in regards to the HTML source code, my code is able to locate <code>itemprop="temperature-fahrenheit"</code> and <code>itemprop="feels-like-temperature-fahrenheit"</code>, but fails on <code>class_="wx-temperature"</code>. I'd appreciate any thoughts about why the first two would succeed but not the third one. Thank you! </p> <p>P.S.: Here is an excerpt of the html source code that is relevant(IMO) to the task at hand:</p> <pre><code>&lt;div class="wx-data-part wx-first"&gt; &lt;div class="wx-temperature"&gt;&lt;span itemprop="temperature-fahrenheit"&gt;87&lt;/span&gt;&lt;span class="wx-degrees"&gt;&amp;deg;&lt;span class="wx-unit"&gt;F&lt;/span&gt;&lt;/span&gt;&lt;/div&gt; &lt;div class="wx-temperature-label"&gt;FEELS LIKE &lt;span itemprop="feels-like-temperature-fahrenheit"&gt;93&lt;/span&gt;&amp;deg;&lt;/div&gt; &lt;/div&gt; &lt;div class="wx-data-part"&gt; &lt;div class="wx-temperature"&gt;94&lt;span class="wx-degrees"&gt;&amp;deg;&lt;/span&gt;&lt;/div&gt; &lt;div class="wx-temperature-label"&gt;HIGH AT 3:25 PM&lt;/div&gt; &lt;/div&gt; &lt;div class="wx-data-part"&gt; &lt;div class="wx-temperature"&gt;76&lt;span class="wx-degrees"&gt;&amp;deg;&lt;/span&gt;&lt;/div&gt; &lt;div class="wx-temperature-label"&gt;LOW&lt;/div&gt; &lt;/div&gt; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
