How to Turn a Json Output of Multiple URLs into a List

In the world of programming, especially when dealing with data, JSON has become a ubiquitous format for data interchange. If you’re a developer, you might find yourself in a situation where you need to extract multiple URLs stored in a JSON structure. Whether you’re working on web scraping, data analysis, or API integrations, having a clean list of URLs can be very beneficial.

In this guide, we’ll cover how to extract these URLs from JSON data and convert them into a list that you can easily manipulate and work with.

The Problem

One common scenario arises when you run a command that pulls out URLs from a JSON object, but you’re left with separate prints of each URL. For example, your current output may look something like this:

Instead of having these URLs in a user-friendly format, you want to compile them into a single list like this:

The Challenge

You may have tried methods like .split(), but these typically just split strings at certain characters, which isn’t helpful in this context. What you need is a way to iterate through the JSON data and collect those URLs into a single list.

The Solution

We can achieve this functionality using Python’s data structures and methods. Here’s how you can effectively turn multiple URLs from a JSON output into a list.

Step 1: Import and Load JSON Data

First, ensure that you import the necessary library and load your JSON data correctly. Assuming you have a JSON string called results, you can use json.loads() to parse it:

Step 2: Create an Empty List

Next, you’ll want to create an empty list to hold all the URLs:

Step 3: Extract URLs Using a Loop

You can then loop through the parsed results and append each URL to the list:

Step 4: (Optional) Use List Comprehension

If you prefer a more concise approach, you can use list comprehension to achieve the same result in one line:

Step 5: Iterate Over the List

After creating your list of URLs, you can easily iterate over them to perform any actions you need, such as printing:

Conclusion

By converting JSON data into a structured list, you can simplify the way you handle URLs in your programming tasks. Whether you use a traditional loop with the append() method or opt for the succinctness of list comprehension, both methods are effective in achieving your goals.

Taking the time to organize your data — like the URLs extracted from a JSON file — can save you plenty of hassle in the long run, allowing you to focus on the more complex tasks at hand. Happy coding!
