Add prices to combobox values and display the total after selection on buttonclick Tkinter-CodePudding

Trying to add prices for different sizes and toppings with button-click to display total order.

def show_answer():
print (box1.get())
print (box2.get())
print (box3.get())

Label (main, text="Select Scoops: ").grid(row=5, column=1)
Scoops =['One','Two','Three']
box2 = ttk.Combobox (main, values=Scoops)
box2.grid(row=5, column=2)

Label (main, text="Select Topping: ").grid(row=7, column=1)
Toppings =['Nuts','Whipped Cream','Cherries']
box3 = ttk.Combobox (main, values=Toppings)
box3.grid(row=7, column=2)

Button (main, text='Order Now', command=show_answer).grid (row=9, column=2, sticky=W, pady=6)

CodePudding user response：

You can use dictionaries to store the prices for different scoops and toppings and then you can calculate the total price based on selected scoop and topping inside show_answer():

...
def show_answer():
    scoop = box2.get()
    topping = box3.get()
    if scoop and topping:
        total_price = Scoops[scoop]   Toppings[topping]
        total_lbl['text'] = f'Total price is ${total_price}'
    else:
        total_lbl['text'] = 'Select both scoop and topping'

Label (main, text="Select Scoops: ").grid(row=5, column=1)
Scoops = {
    'One': 10,
    'Two': 18,
    'Three': 24
}
box2 = ttk.Combobox (main, values=list(Scoops.keys()))
box2.grid(row=5, column=2)

Label (main, text="Select Topping: ").grid(row=7, column=1)
Toppings = {
    'Nuts': 3.5,
    'Whipped Cream': 2.5,
    'Cherries': 5
}
box3 = ttk.Combobox (main, values=list(Toppings.keys()))
box3.grid(row=7, column=2)

Button(main, text='Order Now', command=show_answer).grid(row=9, column=2, sticky=W, pady=6)

# label to show the total price
total_lbl = Label(main)
total_lbl.grid(row=10, column=1, columnspan=2)
