title: Remove commas in list and make a sentence with list items
body: <p>So basically I have a list with 4 items.</p>
  
  <pre><code>list = ['My', 'name', 'is', 'mike']
  </code></pre>
  
  <p>What I want to do is to remove the commas that split the items and make one string. The removed commas should be replaced with space. What I have seen so far is the replace method for string's. I have been wondering if there is something similar for lists.</p>
