title: Remove small words using Python
body: <p>Is it possible use regex to remove small words in a text? For example, I have the following string (text):</p>
  
  <pre><code>anytext = " in the echo chamber from Ontario duo "
  </code></pre>
  
  <p>I would like remove all words that is 3 characters or less. The Result should be:</p>
  
  <pre><code>"echo chamber from Ontario"
  </code></pre>
  
  <p>Is it possible do that using regular expression or any other python function? </p>
  
  <p>Thanks.</p>
