title: Accessing list element without for loop
body: <p>Lets say I have this list</p>
  
  <pre><code>x = [1,10,5,4]
  </code></pre>
  
  <p>and I want to add <code>1</code> for each item of the list. So, the output will be</p>
  
  <pre><code>x = [2, 11, 6, 5].
  </code></pre>
  
  <p>Is there any easy way to do it without using for loop?</p>
