title: Repeat a list within a list X number of times
body: <p>I'm working on a project and I need to repeat a list within a list a certain number of times. Obviously, <code>L.append(L)</code> just adds the elements again without creating separate lists. I'm just stumped on how to make the lists separate within the big list.</p>
  
  <p>In short form, this is what I have:</p>
  
  <pre><code>L = [1,2,3,4,5]
  </code></pre>
  
  <p>If I wanted to to repeat it, say, 3 times so I'd have:</p>
  
  <pre><code>L = [[1,2,3,4,5],[1,2,3,4,5],[1,2,3,4,5]]
  </code></pre>
  
  <p>How do I achieve this? I'm looking for lists within the big list.</p>
