Combine lists by joining strings with matching index values
<p>I have two lists that I would like to combine, but instead of increasing the number of items in the list, I'd actually like to join the items that have a matching index. For example:</p>

<pre><code>List1 = ['A', 'B', 'C']
List2 = ['1', '2', '3']
List3 = ['A1', 'B2', 'C3']
</code></pre>

<p>I've seen quite a few other questions about simply combining two lists, but I'm afraid I haven't found anything that would achieve.</p>

<p>Any help would be much appreciated. Cheers.</p>
