Formulas:
Simple Interest-Principalrate* tmein years/100
Amount Simple Interest +Principal
Use TKinter to bulda GUlapplication that calculates the simple interest forcusromers.
The GUI must take Principal, Rate ofinterest, and Time in years as nputs from the use, and calculate
the Simple Interestas well as the Total Amountin your program at thecick of a button. It must then
display these 2 values on the Gulwindow.
Points will be given basedon how userfnendlyyourGUis. Samakesure younLagels, button, eta have
appropriate text with units f necessary.

from tkinter import *

    #set all the entry boxes to empty
    principle.delete(0, END)

    amount.delete(0, END)

    #calculate simple interest
    si = (p*r*t)/100
    #insert it to entry box
    interest.insert(10, si)

    a = si+p
