get text from <span> with beautiful soup
<p>I want to get text from span tag but i have such problems. 
I wrote this, </p>

<pre><code>import bs4 as bs
import urllib.request

page = urllib.request.urlopen('http://www.accuweather.com/en/az/baku/27103/current-weather/27103').read()

soup = bs.BeautifulSoup(page, 'html.parser')

print(soup.find_all('li', class_='wind'))
</code></pre>

<p>and it returned like that <code>[&lt;li class="wind"&gt;&lt;strong&gt;28 km/h&lt;/strong&gt;&lt;/li&gt;]</code></p>

<p>but I want to get just "28 km/h"</p>

<p>then I tried that </p>

<pre><code>page = urllib.request.urlopen('http://www.accuweather.com/en/az/baku/27103/current-weather/27103').read()

soup = bs.BeautifulSoup(page, 'html.parser')

print(soup.find_all("span" , { "class" : "wind" }))
</code></pre>

<p>but it did not work either. Please help me with it.</p>
