How to Update a Dictionary with Different List Elements in Python
Creating and updating dictionaries in Python is a common task, especially when handling structured data. In this guide, we'll explore how to generate a dictionary with multiple list elements—specifically focusing on a situation where the keys remain constant, but the values vary according to different data lists.
The Problem
Suppose you want to create a dictionary that structures audio file information. You'd like the dictionary to display each filename as a key, and for each filename, there should be an inner dictionary containing name and embedding. The catch is that the values for name and embedding change depending on the filename. Here's the desired structure:

However, using the initial code provided yields unexpected results, wherein all entries in the dictionary point to the same inner dictionary object.
The Solution
To achieve the correct structure where each filename correctly represents its corresponding name and embedding, follow these steps:
Understanding the Issue
Reference Overwrites: The initial code was overwriting the same inner_dict for each filename, meaning every entry in outer_dict ended up referencing the last inner_dict created.
Nested Loops: The nested loops used to assign name and embedding were causing all entries to reflect the last values in their respective lists.
Step-by-Step Guide
Here's how to structure the dictionary correctly:
Step 1: Initialize Your Variables
Prepare lists for audio filenames, speaker IDs, and embeddings that will be used to structure the final dictionary.

Step 2: Create the Outer Dictionary
Set up the outer dictionary that will hold the filenames as keys.

Step 3: Populate the Dictionary
Loop through the range of audio filenames while creating a new inner_dict for each filename.

Final Code Example
Here is the complete code that combines all the above steps:

Expected Output
When you run the code, you will get the expected structured dictionary:

Conclusion
By creating a new inner dictionary during each iteration of the loop, we ensure that every entry in outer_dict points to a unique object reflecting the intended structure. This approach will help you effectively manage dynamic data in your applications. Happy coding!
