How to Check If a JSON Object Is Empty in Python

In this tutorial, we will guide you through the process of checking whether a JSON object is empty using Python. JSON (JavaScript Object Notation) is a common open-standard file format or data interchange format that uses human-readable text to transmit data objects consisting of attribute-value pairs and arrays, or other serializable values.

While working with JSON data, it’s common to encounter a situation where you need to determine if a JSON object is empty or not. Python provides straightforward ways to handle this.

Prerequisites:

Before you start, make sure you have a working Python installation on your computer. If you need help installing Python, you can refer to the official Python website.

Step 1: Create a JSON Object

First, we need a JSON object that we will use to check if it is empty or not. Here’s how you can create a JSON object in Python:

1
2
3

5
user_info = {
    "name": "John Doe",
    "age": 30,
    "city": "New York"
}

Step 2: Check If JSON Object Is Empty

To check if the JSON object is empty, we will use the len() function provided by Python, which gives the length of the object. If the length is 0, it means that the object is empty:

1
2
3
4
if len(user_info) == 0:
    print("The JSON object is empty.")
else:
    print("The JSON object is not empty.")

The output will be “The JSON object is not empty.” because our user_info JSON object contains some data.

}
 
if len(user_info) == 0:
    print("The JSON object is empty.")
else:
    print("The JSON object is not empty.")

Conclusion

In this tutorial, you’ve learned how to check if a JSON object is empty in Python. This is a useful piece of knowledge when you’re dealing with JSON data in Python, as it allows you to handle different cases depending on whether the JSON object has data or not.
