Change Background Color with Radio Button in Tkinter

In this post you will learn to click the radio button and to change the background color according to the radio button you clicked.

When the radio buttons are clicked , the lambda function works. In the lambda function, the “color” function takes a parameter the is the color of background.


from tkinter import *

root = Tk() 
root.title("Change background color with radio button")

def changeColor(color): 
    root.configure(background =color)
    choice1.configure(background =color) 
    choice2.configure(background =color)
    choice3.configure(background =color)
    choice4.configure(background =color)

v =StringVar()
v.set("L")

choice1 =Radiobutton(root, text ="red", value =1, variable =v, command =lambda: changeColor("red"))
choice1.grid(row =0, column =0) 

choice2 =Radiobutton(root, text ="blue", value =2, variable =v, command =lambda: changeColor("blue"))
choice2.grid(row =1, column =0)

choice3 =Radiobutton(root, text ="yellow", value =3, variable =v, command =lambda: changeColor("yellow"))
choice3.grid(row =2, column =0)

choice4 =Radiobutton(root, text ="green", value =4, variable =v, command =lambda: changeColor("green"))
choice4.grid(row =3, column =0)

root.mainloop()
