title: Accessing Airflow Variable in List format
body: <p>i have this Variable on Airflow</p>
  <pre><code>['item_1', 'item_2']
  </code></pre>
  <p>then i get the variable</p>
  <pre><code>my_var = Variable.get('my_var')
  </code></pre>
  <p>and then i try to loop it like this</p>
  <pre><code>for var in my_var:
      print(var)
  </code></pre>
  <p>it prints the character one by one.</p>
  <p>My question is: how do i access the list value? without printing the character one by one</p>
