Merging Two Python Dictionaries: A Simple Guide

When working with Python, you may find yourself needing to combine multiple dictionaries into one. This often arises when you're dealing with JSON data, where you have separate dictionaries that you want to merge for easier access or storage. In this guide, we’ll explore how to merge two different Python dictionaries into a single one and save the result in a JSON file.

Understanding the Problem

Let’s say you have two dictionaries: one containing audio properties and another holding reference timestamps. Here’s how these dictionaries look:

Unfortunately, if you’re not careful with the merging process, you might end up with extra brackets or an incorrect structure, which can lead to errors in your JSON file later on.

Solution: Merging Dictionaries Successfully

Step 1: Using the Spread Operator

If you are using Python 3.6 or later, you can easily merge dictionaries using the unpacking feature. Here is how you can do that:
