Creating Multiple Files from Two Lists in Python

In the world of programming, working with files is a common task. If you find yourself needing to create multiple output files from two separate lists, this guide will help you do just that with Python. We will tackle how to read from two lists (in file form), manipulate data, and generate new files based on these inputs.

Problem Overview

Example Scenario

You aim to produce three JSON files as follows:

Solution Strategy

To achieve this, we need to follow some clear steps:

Replace Placeholders: Replace designated placeholders in the template with the corresponding values from the lists.

Write Output Files: Save each modified configuration to a new JSON file.

Step-by-Step Implementation

Step 1: Read the Input Files

Using Python's built-in file handling, you can read the contents of both the BAM and BAI files into lists.
