How To Get Value From JSON Response In Python

In this tutorial, we’ll learn how to extract value from a JSON response using Python. JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate.

It is a popular format for exchanging data in modern web applications. In Python, we can use the JSON module to parse and extract values from JSON data.

Step 1: Importing the JSON module

The first step is to import the JSON module. This module comes pre-installed with Python and doesn’t require any additional installation. You can import it using the following command:

1
import json

Step 2: Convert JSON data to Python object

We will use the json.loads() method to convert the JSON data to a Python object. This will help us easily access the data in Python.

2
json_data = '{"name": "John", "age": 30, "city": "New York"}'
python_obj = json.loads(json_data)

In this example, json_data is a string that represents JSON data. The json.loads() method takes a valid JSON string and converts it into a Python object, which we store in the python_obj variable.

Step 3: Accessing a specific value from the JSON data

Now that we have the JSON data loaded as a Python object, we can access and extract specific values using the appropriate data structure operations. In this case, we have a dictionary.

1
name = python_obj["name"]

In this example, we extract the value of the "name" key from the Python dictionary python_obj. The extracted value is stored in the name variable.

Step 4: Print the extracted value

Finally, we can print the extracted value using the print function.

1
print("Name:", name)

This will print the extracted value of the name key from the JSON data.

import json
 
json_data = '{"name": "John", "age": 30, "city": "New York"}'
python_obj = json.loads(json_data)
 
name = python_obj["name"]
 
print("Name:", name)

Output

Name: John

Conclusion

In this tutorial, we have learned how to extract values from a JSON response using Python.

We used the JSON module to parse and load the JSON data into a Python object and then accessed specific values from the object as needed. This method is useful when working with APIs and web applications that return data in JSON format.
