Save json File in Python

The save data as a JSON file in Python, you can use the json module, which provides methods for encoding Python data structures into JSON format and writing them to a file. Here’s a step-by-step guide:

1. Import the json module:

import json

2. Create a Python data structure (e.g., a dictionary or a list) that you want to save as a JSON file.

data = {
    "name": "John",
    "age": 30,
    "city": "New York"
}

3. Specify the file path where you want to save the JSON data. Make sure to include the file extension “.json”.

file_path = "data.json"

4. Open the file in write mode ("w") using a with statement, and use the json.dump() function to write the data to the file.

with open(file_path, "w") as json_file:
    json.dump(data, json_file)

Here’s the complete code:

import json

data = {
    "name": "John",
    "age": 30,
    "city": "New York"
}

file_path = "data.json"

with open(file_path, "w") as json_file:
    json.dump(data, json_file)

After running this code, you will have a JSON file named “data.json” in your current working directory with the contents of the data dictionary.

You can also use the json.dumps() function to convert a Python data structure to a JSON-formatted string, which you can then save to a file manually:

import json

data = {
    "name": "John",
    "age": 30,
    "city": "New York"
}

json_string = json.dumps(data)

file_path = "data.json"

with open(file_path, "w") as json_file:
    json_file.write(json_string)

This code will achieve the same result, with the data saved in “data.json.”
