title: How to extract words from a text using python?
body: <p>I need to extract the words and phrases within a text. For example, the text is:</p>
  
  <pre><code>Привет, hello, как дела? english word, еще одно русское слово, слово-1224, тест 4456
  </code></pre>
  
  <p>And script should return the following:</p>
  
  <pre><code>Привет
  как
  дела
  еще
  одно
  русское
  слово
  слово-1224
  </code></pre>
  
  <p>That is, I need to take from the text of all the words that begin with the Russian letters (<code>[а-яА-Яё-]</code>), and can contain numbers and letters of the Russian alphabet. How is this implemented?</p>
