title: Iterate through two 2d arrays
body: <p>i have two 2d arrays and i want to iterate through them both and store the values in a new array
  for example:</p>
  <pre><code>days = [[&quot;monday&quot;, &quot;11:00&quot;],
          [&quot;monday&quot;, &quot;13:00&quot;],
          [&quot;tuesday&quot;, &quot;10:00&quot;]] 
  </code></pre>
  <p>and my other array:</p>
  <pre><code>modules = [[&quot;chemistry&quot;, &quot;alkenes&quot;],
             [&quot;biology&quot;, &quot;alcohols&quot;],
             [&quot;biology, cells&quot;]]
  </code></pre>
  <p>i want the new arrays output to be</p>
  <pre><code>[&quot;monday&quot;, &quot;11:00&quot;, &quot;Chemistry&quot;, &quot;alkenes&quot;] 
  </code></pre>
  <p>currently my code looks likes this:</p>
  <pre><code>for x in days:
      newarray = []
      for i in modules:
          newarray.append(x)
          newarray.append(i)
  </code></pre>
  <p>but this doesn't work so how would i create this new array</p>
