The themed widgets from Tkinter will be used from now on, so the additional import in the code below.
The function increment, defined in the code, adds 1 to value currently held in a label.
Here, there are 3 widgets in total, within the Frame widget.
The 3 widgets take 3 of the 4 positions in a 2 by 2 grid. The button widget has text ‘+’ and pressing it will invoke the increment function.
There are 2 labels. The first has the name label and is static with text of ‘Counter’. The second, label1, can have the text updated using a StringVar object. We initialize it as ‘0’ and update via the increment function.
from tkinter import *
from tkinter.ttk import *
a = int(counter.get())
frame = Frame(root)
button = Button(frame, text='+',
command = increment, pad = 5)
button.grid(row = 1, column= 0)
label = Label(frame, text = 'Counter', pad = 5)
label.grid(row = 0, column = 1)
counter = StringVar()
label1 = Label(frame, textvariable = counter, pad = 5)
label1.grid(row = 1, column = 1)
