How to Create Json File Dynamically in Python: Only 6 Steps

JSON is the most used as response among various apps for development. Do you want to create JSON File Dynamically in Python? If yes then this post is for you. In this tutorial you will know how to create JSON File dynamically in python using step by step.

Problem Statement

You are getting JSON response dynamically on your app and want to create JSON File for that dynamically in python.

Steps to Create Json File Dynamically in Python

Let’s know all the steps you will follow to save JSON file dynamically in Python.

Step 1: Import the required library

The first step is to import all the necessary modules for implementation. In this tutorial I am using the JSON module so let’s import it using the import statement.

import json

Step 2: Create an empty dictionary

The next step is to create an empty dictionary that will store the key-value pair for JSON response. Use the below line of code to create an empty dictionary.

data ={}

Step 3: Define the key-value

Now the next step is to define the key-value pair for the dictionary. It is done only to store that data dynamically to the dictionary.

data['key'] = 'value'

Step 4:  Convert the dictionary to JSON data

Now after adding the data dynamically to the dictionary, you have to convert the dictionary to JSON using the json.dumps() function. Just pass the input dictionary as the argument.

json_data = json.dumps(data)

Step 5: Specify the path to write the JSON file

After the conversion you will save the JSON file to a specific path. Define the path as as string.

file_path = "path/to/your/file.json"

Step 6: Write JSON data to file

Now the last data is to write the Json data to file. For this you have to use the open() function with “w” as write mode and use the write() function to save the JSON to the file.

with open(file_path, 'w') as json_file:
    json_file.write(json_data)

Full Code

import json
data ={}
data['key'] = 'value'
json_data = json.dumps(data)
file_path = "data.json"
with open(file_path, 'w') as json_file:
    json_file.write(json_data)

Output

Conclusion

Thats all you have to save JSON file dynamically in Python. JSON response allows you to use and manipulate the application easily. The above steps will help you to save Json File Dynamically in Python.
