Bug-Fixing Exercise 1

The program down below is supposed to convert kilometers to miles.

import PySimpleGUI as sg


def km_to_miles(km):
    return km / 1.6


label = sg.Text("Kilometers: ")
input_box = sg.InputText(tooltip="Enter todo", key="kms")
miles_button = sg.Button("Convert")

output = sg.Text(key="output")


window = sg.Window('Km to Miles Converter',
                   layout=[[label, input_box], [miles_button, output]],
                   font=('Helvetica', 20))

while True:
    event, values = window.read()
    match event:
        case "Convert":
            km = values["kms"]
            result = km_to_miles(km)
            window['output'].update(value=result)
        case sg.WIN_CLOSED:
            break

window.close()

However, when the user runs the code above, enters a number, and presses the Convert button, the program stops, and an error is displayed in the command line:

TypeError: can't multiply sequence by non-int of type 'float'

Place the code in your IDE and try to troubleshoot and fix the error.
