read_json - Python

Introduction:

The read_json function in Python is a convenient way to read data from a JSON file. 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. With the read_json function, you can load JSON data into Python and access it as a Python object.

Usage:

To use the read_json function, you need to follow these steps:

1. Import the required library:

import json

2. Define a function to read JSON data from a file:

def read_json(file_path):
    with open(file_path) as f:
        data = json.load(f)
    return data

3. Call the function to read JSON data from a file:

json_data = read_json('path/to/your/file.json')

Parameters:

The read_json function takes a single parameter, which is the path to the JSON file that you want to read.

• file_path: The path to the JSON file. This can be a relative or absolute path.

Return value:

The read_json function returns the JSON data loaded as a Python object. The returned object can be accessed and manipulated using Python's built-in data structures and methods.

Example:

Consider an example where you have a JSON file named 'data.json' with the following content:

{
    "name": "John Doe",
    "age": 25,
    "city": "New York"
}

Using the read_json function, you can load this data into Python as follows:

data = read_json('data.json')
print(data)

The output will be:

{"name": "John Doe", "age": 25, "city": "New York"}

Now, you can access specific elements of the JSON data using standard Python syntax. For example, to print the name:

print(data['name'])

The output will be:

John Doe

Markdown code:

You can use the `read_json` function to read JSON data from a file in Python. It returns the loaded JSON data as a Python object, allowing you to easily access and manipulate the data. The function takes the file path as a parameter and requires the `json` library to be imported. Here is an example of how to use it:

```python
import json

def read_json(file_path):
    with open(file_path) as f:
        data = json.load(f)
    return data

json_data = read_json('path/to/your/file.json')
print(json_data)

In this example, the function reads the JSON data from the file and returns it as a Python object, which is then printed. You can access specific elements of the JSON data using standard Python syntax.
