Tkinter: is there a way to check checkboxes by default?

Question

I have this piece of code that will create a simple checkbox :

from Tkinter import *

CheckVar = IntVar()
self.checkbutton = Checkbutton(self.root, text = \"         


        

Answer 1

var4 = IntVar(value=1)
    Checkbutton(root, text="New", variable=var4, bg="light green").grid(row=12, column=0)

This code will check all the boxes when you run the program.
