title: Python list as a list indices
body: <p>Suppose we have two lists </p>
  
  <pre><code>list_A = [1,3,4,54,3,5,6,2,6,77,73,39]
  list_B = [0,3,2,8]
  </code></pre>
  
  <p>I want to access elements of <code>list_A</code> that have the values in <code>list_B</code> as their indices (without using loops).</p>
  
  <p>After implementing it, the result should be as follows for the above case:</p>
  
  <pre><code>[1, 54, 4, 6]
  </code></pre>
  
  <p>Is there any easy method to do this without bothering with <code>for</code> loops (calling it explicitly in the code) ?</p>
