jsonatago: JSONata for Python

jsonatago is a Python library that enables you to evaluate JSONata expressions. This project aims to bring the power and flexibility of JSONata to Python developers.

Credits

This project uses the Go implementation of JSONata from jsonata-go. All credit for the Go implementation goes to the authors and contributors of jsonata-go.

Installation

To install jsonatago, you can use pip:

pip install jsonatago

Usage

Here's a simple example that demonstrates how to evaluate a JSONata expression:

python

from jsonatago import Jsonata

JSONATA_TEST_DATA = {
    "Account": {
        "Order": [
            {"Product": [{"Price": 10, "Quantity": 2}, {"Price": 5, "Quantity": 5}]},
            {"Product": [{"Price": 20, "Quantity": 1}, {"Price": 15, "Quantity": 3}]}
        ]
    }
}
expr = Jsonata("$sum(Account.Order.Product.(Price * Quantity))")
print(expr.evaluate(JSONATA_TEST_DATA))

This will output the sum of all Price * Quantity for each product in each order.

You can use as well direct method for compilation and evaluation in one step. python

from jsonatago import jeval

JSONATA_TEST_DATA = {
    "Account": {
        "Order": [
            {"Product": [{"Price": 10, "Quantity": 2}, {"Price": 5, "Quantity": 5}]},
            {"Product": [{"Price": 20, "Quantity": 1}, {"Price": 15, "Quantity": 3}]}
        ]
    }
}
print(jeval(JSONATA_TEST_DATA,"$sum(Account.Order.Product.(Price * Quantity))"))
