<h3>Python Data Types Overview</h3>
<p>Python supports various data types that determine the kind of operations that can be performed on a value.</p>
<ol>
<li>
<p><strong>Numeric Types</strong>:</p>
<ul>
<li><strong>Integer (<code>int</code>)</strong>: Whole numbers.
<div class="dark bg-gray-950 contain-inline-size rounded-md border-[0.5px] border-token-border-medium relative">
<div class="flex items-center text-token-text-secondary bg-token-main-surface-secondary px-4 py-2 text-xs font-sans justify-between rounded-t-md h-9">
<pre class="language-python"><code>age = 25  # Integer</code></pre>
</div>
</div>
</li>
<li><strong>Float (<code>float</code>)</strong>: Numbers with decimal points.
<div class="dark bg-gray-950 contain-inline-size rounded-md border-[0.5px] border-token-border-medium relative">
<div class="flex items-center text-token-text-secondary bg-token-main-surface-secondary px-4 py-2 text-xs font-sans justify-between rounded-t-md h-9">
<pre class="language-python"><code>pi = 3.14  # Float</code></pre>
</div>
</div>
</li>
<li><strong>Complex (<code>complex</code>)</strong>: Complex numbers with a real and imaginary part.
