import listpicker

pizza_styles = ("Thin crust", "Stuffed crust", "Deep dish")
style = listpicker.pick("Choose pizza style:", pizza_styles)

# User can abort input, so handle the case where "pick()" returns "None"
if style is None:
    style = pizza_styles[0]

pizza_toppings = ("Pepperoni", "Sausage", "Mushroom", "Pineapple")
toppings = listpicker.pick_multiple("Choose toppings:", pizza_toppings)
