How do I make a PySimpleGUI calculate the options?

Question

Trying to make the GUI application calculate cost. Unsure how to do it

So I've built my GUI Application using PySimpleGUI but i'd like to make it functional and calculate the total membership cost in the pop up window I've created. Can someone point me in the right direction? How do I apply numerical values to radio buttons and checkboxes to calculate costs?

Thanks! sorry I'm very new to this so I'm not well versed in Python.

Most of time, I use dictionary to map the item to a value for calculation later. With enable_Events=True in Checkbox or Radio element, or another Submit Button, to generate an event when click for the calculation and GUI update.

import PySimpleGUI as sg

discounts = {"75%":0.75, "85%":0.85, "95%":0.95, "No":1.0}
prices = {"Summer Dress":545, "Coat":275, "Elegant Suit":685, "Casual Shirt":98, "Bridesmaid Dress":440, "Shoes":195}

layout = [
    [sg.Text("Discount")],
    [sg.Radio(discount, "Discount", enable_events=True, key=("Discount", discount)) for discount in discounts],
    [sg.Text("Price List")]] + [
    [sg.Checkbox(price, enable_events=True, key=("Price", price)), sg.Push(), sg.Text(prices[price])] for price in prices] + [
    [sg.Text("Total: 0", justification='right', expand_x=True, key='Total')],
]

window = sg.Window('Example', layout)

while True:

    event, values = window.read()

    if event == sg.WIN_CLOSED:
        break
    elif isinstance(event, tuple) and event[0] in ('Discount', 'Price'):
        dis = 1
        for discount in discounts:
            if values[('Discount', discount)]:
                dis = discounts[discount]
                break
        total = sum([prices[price] for price in prices if values[("Price", price)]])
        window['Total'].update(f"Total: {int(total*dis)}")

window.close()
