title: list removal and merge in one line
body: <p>In python, I want to <strong>remove one item</strong> from a list and then <strong>merge</strong> this list to a new one. Can I chain methods so this happens <strong>in one line</strong>?</p>
  
  <p>For instance:</p>
  
  <pre><code>a = [1,2,3,4]
  # I want to remove 3 and add [10,11]
  a.remove(3) #it doesn't return a, so I can't do this in one line
  a += [10,11]
  </code></pre>
