How to Correctly Display Two Number Text Files in Python: A Step-by-Step Guide

When working with multiple text files in Python, especially when they contain numerical data and textual information, it's easy to run into formatting issues that may cause confusion. A common problem presents itself when the output gets misaligned, often due to how we handle the end of lines and whitespace in our data.

The Problem

The user's code aimed to read content from the three files and print them in a structured manner. However, they encountered missing or misaligned text:
