title: Python | How to remove sub array from 2D array
body: <p>If I have a 2D array like:</p>
  
  <pre><code>array = [["hello"], [1,2,3], [4,5,6]]
  </code></pre>
  
  <p>How can I get the program to remove the first sub array so that it turns out like this:</p>
  
  <pre><code>array = [[1,2,3], [4,5,6]]
  </code></pre>
  
  <p>If I try to do <code>array[0].pop[0]</code>, the array ends up like this:</p>
  
  <pre><code>array = [[], [1,2,3], [4,5,6]]
  </code></pre>
