Your way of teaching each topic step by step is awesome

[IAMVEGETA]

harry you are great programming teacher
here is your exercise code -
from tkinter import *
tk = Tk()

def resize():

if width==0:
print("0 cant be done ")
if height==0:
print("0 cant be done ")

tk.geometry("200x100")
w = Label(tk, text="width - ").grid(row=1, column=1)
h = Label(tk, text="height - ").grid(row=2, column=1)

widthgetvalue = StringVar()
heightgetvalue = StringVar()

width =
height =

width.grid(row=1, column=2)
height.grid(row=2, column=2)

resizer = Button(tk, text="Done", command=resize)
resizer.grid(column=2)
