How to Remove a Certain Number from Output in Python Code

When working with Python, you may come across a scenario where you need to manipulate string outputs involving chapter and verse numbers, especially in contexts such as books or similar structured data. One of our readers faced such a challenge—they wanted to remove a specific number from the output of their code while keeping the first number intact. In this guide, we will walk through how to achieve this using the Python programming language.

Understanding the Problem

The user provided a function that generates chapter and verse references in a format represented by numbers separated by periods. The goal is twofold:

Subtract a specific number (-7) from every chapter and verse except for the first chapter number.

Ensure it works for larger numbers and multiple numbers seamlessly.

Here is the initial output they provided after running their code:

Proposed Solution

Let's break down how to resolve this step-by-step. The strategy used during this process involves iterating through the string representations of the numbers, identifying which are digits, and adjusting them appropriately.

Step 1: Initializing Variables

You need to have the original list ready to work with:
