I most frequently use List Comprehensions in a nested manor, whenever I do that I &#x2F;ignore&#x2F; the normal python syntax and do this for readability.<p><pre><code>    inserts = [ a + c + b
                for a, b in splits
                for c in alphabet ]
</code></pre>
It has the effect of showing the nested loops stacked like they would be in code, but without intending.
