How to Compare a Three Tiers Dictionary in Python and Print Only Non-Matching Values

In Python, dictionaries are a popular data structure that allows you to store and manipulate data in key-value pairs. However, comparing dictionaries, especially when they are nested or multi-tiered, can be challenging. In this guide, we will explore how to compare two three-tier dictionaries in Python and print only the values that do not match.

The Problem

Let's say you have two dictionaries, RT and AA, each containing solutions to various services like flights and hotels. The structure is as follows:

Your goal is to compare these dictionaries and print the differences in values clearly. For example, you expect an output such as:

The Solution

To achieve this, we need to iterate through both dictionaries and compare the values in a structured manner. Below is a step-by-step breakdown of how we can implement this in Python.

Step 1: Initialize Data Structures

Create an empty dictionary named ans to store the differences we find. This will hold the keys along with their differing values.

Step 2: Iterate Over the First Dictionary

Using nested loops, iterate over the keys and values of the first dictionary (RT). This helps in accessing each nested dictionary easily.

Step 3: Compare Corresponding Values

For each value in the first dictionary, check if it exists in the second dictionary (AA). If it does, compare the values:

If they differ, append both values to a list and store this list in ans.

If the key does not exist in AA, append the original value and "N/A" to indicate that there is no corresponding element in AA.

Step 4: Print Results

Finally, print the collected differences stored in the dictionary ans.

Example Code

Here's how the code looks that implements the above logic:

Conclusion

By following the above approach, you can effectively compare nested dictionaries in Python and highlight only the mismatched values. This method can be particularly useful in scenarios where you need to identify differences in configurations, responses, or data sets.

Now that you understand how to compare three-tier dictionaries in Python, go ahead and implement it in your projects! Happy coding!
