function in new window (tkinter)

[Dale22]

Hi I'm new to python
I'm trying to create a widget that performs a calculation on clicking a button, only I want the function to open in a new window. can anyone help me please? as you can see I've put the function into button 1 but I don't know how to open it in a new window.
Thanks

master=tkinter.Tk()
master.title("Carpet shop")
master.geometry("400x500")
master.configure(bg='peach puff')


def callback():
    w = float(input('carpet width:'))
    l = float(input('carpet length:'))
    p = float(input('carpet price:'))
        

    p1 = w*l*p #carpet only
    p4 = max(30,(w*l*f)) #fitting
    p2 = w*l*p + max(30,(w*l*f)) #carpet and fitting
    p3 = w*l*p + max(30,(w*l*f)) + w*l*u #carpet underlay and fitting
    p5 = w*l*p + max(30,(w*l*f)) + w*l*u + 10 #carpet, underlay, grips and fitting
