title: Pythonic way to append multiple values to a list
body: <p>To be clear I have found some similar questions, but (to the best of my knowledge) none of them are either concise enough or exactly what I am looking for.</p>
  
  <p>I have a list(of ints) and two other ints, and want to make them all into one list. Right now I have:</p>
  
  <pre><code>old_list = [1, 2, 3]
  first_int = 3
  second_int = 5
  
  new_list = old_list
  new_list.append(first_int)
  new_list.append(second_int) 
  
  # new_list == [1, 2, 3, 3, 5]
  </code></pre>
  
  <p>I feel that there is a more Pythonic way to do this but I am unsure exactly how.<br>
  The order of 'new_list' is not important.</p>
  
  <p>Thank you in advance.</p>
