Background color for Tk in Python

python tkinter tk

root.configure(background='black')

or more generally

<widget>.configure(background='black')

python tkinter tk

I know this is kinda an old question but:

root["bg"] = "black"

will also do what you want and it involves less typing.

python tkinter tk

Its been updated so

root.configure(background="red")

is now:

root.configure(bg="red")
