<h2 class="wp-embed-aspect-16-9 wp-has-aspect-ratio">Problem Formulation and Solution Overview</h2>
<p class="wp-embed-aspect-16-9 wp-has-aspect-ratio">This article will show you how 6 ways to remove <a rel="noreferrer noopener" href="https://blog.finxter.com/python-lists/" target="_blank"><code>List</code></a> elements in Python.</p>
<p>To make it more interesting, we have the following running scenario:</p>
