title: How can I add some strings to a list that already exists in Python?
body: <pre><code>list1 = ['1', '2', '3', '4']
  input_list = ['5', '6']
  </code></pre>
  <p>the output I want is:</p>
  <pre><code>print(list1)
  &gt;&gt; ['1','2','3','4','5']
  &gt;&gt; ['1','2','3','4','6']
  </code></pre>
  <p>I tried many other things, but I couldn't get the result I want..
  I also searched other Q&amp;As to find the way, but I couldn't find as well..
  Thanks for your help!</p>
