Mastering JSON Edits in Python: A Step-by-Step Guide

Working with JSON files in Python is a common task for developers, especially when dealing with data that needs to be modified or analyzed. Today, we'll address a particular challenge: how to modify the last data entries of specific keys in a JSON object.

The Problem

Suppose you have a JSON structure like this:

[[See Video to Reveal this Text or Code Snippet]]

Your goal is to increase the last numeral in the street1 and sttreet2 entries by 10. After the modification, your JSON should look like this:

The Solution

There are multiple ways to achieve this JSON modification in Python. Below, we'll outline two methods: a generalized approach that works for any number of entries, and a more manual method.

Method 1: Generalized Approach

In this method, we’ll iterate through each address and update the last part of the street value.

Set up your JSON data:

First, initialize the JSON structure you want to modify.

Loop through the address list:

Use a nested loop to access each key in the address entries. By doing so, we'll modify the last two digits of each street.

Run the code:

After executing this code, your modified JSON will be:

Method 2: Manual Approach

If you prefer a more manual and straightforward approach, you can specify each key directly:

Update street1

After this update, you'll see:

Update sttreet2

Similarly, for the second street:

Now, the final output will be:

Conclusion

Editing JSON files in Python doesn't have to be a complex task. With either the generalized approach or the manual method described above, you can easily modify specific values in your JSON data. By practicing these techniques, you'll enhance your data manipulation skills and streamline your workflow for any future JSON handling tasks.
