Pair List Elements with Zero: A Small Data Transformation Helper

Today, I'm sharing a new small helper I've built: Pair List Elements with Zero. This tool addresses a specific data transformation need that comes up in some contexts.

What it does:

Pair List Elements with Zero takes an input list and transforms it into a new list. The output consists of two-item sublists. Each sublist is structured with 0 as its first element, followed by an element from the original input list. So, if your original list was [A, B, C], the output would be [[0, A], [0, B], [0, C]].

Who is this for?

This helper is useful for developers or anyone working with data structures who needs to prepare a list for subsequent operations that require a specific two-item nested list format. For instance, when you need to introduce a consistent starting value (like zero) alongside each existing element for indexing, mapping, or other programmatic manipulations of nested lists. It simplifies a common, repetitive data preparation step.

It's a focused tool designed to do one thing: standardize the pairing of list elements with a leading zero. I built it for situations where this exact transformation is needed regularly.
