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.

AJAX with JavaScript: A Practical Guide

Before the Fetch API, the traditional way to make AJAX requests was using XMLHttpRequest.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>AJAX with XMLHttpRequest</title>
</head>
<body>
    <button id="fetchDataBtn">Fetch Data</button>
    <div id="dataOutput"></div>

    <script>
        document.getElementById('fetchDataBtn').addEventListener('click', function() {
            var xhr = new XMLHttpRequest();
            xhr.open('GET', 'https://jsonplaceholder.typicode.com/posts/1', true);

            xhr.onload = function() {
                if (this.status === 200) {
                    var data = JSON.parse(this.responseText);
                    document.getElementById('dataOutput').innerHTML = `
                        <h3>${data.title}</h3>
                        <p>${data.body}</p>
                    `;
                }
            };

            xhr.onerror = function() {
                console.error('Request failed.');
            };

            xhr.send();
        });
    </script>
</body>
</html>
