Python is already used in the back-end of most web-based applications. However, it does not work with the front-end of web browsers in those applications. This is where Transcrypt comes in. Transcrypt can help create more coherent web-based projects where Python is used to write the back-end and front-end. This course is primarily about using a transpiler called Transcrypt. It translates our Python code to JavaScript and then executes that JavaScript, letting us enjoy the neatness of Python with the front-end flexibility of JavaScript.

Using the Python Transcrypt Transpiler for Front-end Coding

## Problem statement


Currently our application takes input and shows it in an `alert()` dialog box.
With the way we are using the `pyreact.py` module as a bridge between Python and
JavaScript, it becomes easy to make more JavaScript functions available to our pure Python
modules. 

For this code challenge, instead of just showing an `alert()`, we are going to add a confirmation prompt instead. This will either
return `True` or `False` depending on whether “OK” or “Cancel” was clicked in the
confirmation.

Starting with `pyreact.py`, add a Python reference for the JavaScript
`window.confirm()` function similar to how we added the one for `alert()`.

Next, update the `import` statement and modify the `handleSubmit()` function in `app.py` to show the confirm box instead of the alert. Change the displayed
message to ask if the item should be added or not. Display the result of the confirm dialog
in the web browser only when the user selects “OK” in the dialog box. Otherwise, the input should be discarded.
