Promise-based Execution of Python Code with jsPython

// Call the jsPython function to get an evaluator object
const evaluator = jsPython();

// Define the Python code you want to evaluate
const codeToEvaluate = `
print("Hello from Python!")
`;

// Evaluate the code and handle the resulting Promise
evaluator.evaluate(codeToEvaluate)
    .then(
        // This arrow function runs if the evaluation is successful
        result => {
            console.log('Result =>', result);
        },
        // This arrow function runs if the evaluation fails
        error => {
            console.log('Error =>', error);
        }
    );

Explanation:

1. jsPython(): This function is presumed to return an object that can evaluate Python code from within JavaScript.
2. evaluate(codeToEvaluate): Pass the Python code (as a string) to the evaluate method. This returns a Promise.
3. .then(...): When the Promise settles, .then() is called.

• The first callback (result => { ... }) handles the resolved value, printing out the result.
• The second callback (error => { ... }) handles any rejected value (errors), printing out the error message.
