Write a Python GUI program to calculate volume of Sphere
by accepting radius as input.
from tkinter
import *
def volumesphere():
res=4.0/3.0 *3.14 * int(e1.get())**3
label_text.set(res)
window = Tk()
label_text=StringVar();
Label(window, text="Enter Radius Number:").grid(row=0)
Label(window, text="Result:").grid(row=3)
result=Label(window, text="", textvariable=label_text).grid(row=3,column=1)
e1 = Entry(window)
e1.grid(row=0, column=1)
b = Button(window, text="Calculate", command=volumesphere)
b.grid(row=0, column=2,columnspan=2, rowspan=2, padx=5, pady=5)
mainloop()
