How to Handle JSON NULL in Python

To handle the JSON NULL, you can use the json.loads() method. It returns the null equivalent of Python None.

Here are the step-by-step instructions you need to follow:

Step 1: Parsing JSON Data

You can parse JSON data by importing the json module.

import json

# Example JSON string with null
json_string = '{"name": "Calvin", "age": null, "name": "USA"}'

# Parsing JSON string
data = json.loads(json_string)

print(data)

Output

{'name': 'Calvin', 'age': None, 'country': 'USA'}

You can see that null is automatically converted to None.

Step 2: Handling None in Data Processing

When performing operations on data, ensure that you include checks or use try-except blocks to catch exceptions that may occur due to None values.

import json 

json_string = '{"name": "Calvin", "age": null, "country": "USA"}'

# Parsing JSON string
data = json.loads(json_string)

# Check and handle the null/None value
age = data.get('age')
if age is not None:
 print("Age is:", age)
else:
 print("Age is not provided or is null.")

Output

Age is not provided or is null.
