tkinter- Applying random function(from a couple of them) on a text widget everytime the program starts : So i created a couple of functions, to change the theme of my application, and some examples are given below:

    def redtheme():
    text.config(background="light salmon", foreground="red",
                insertbackground="red")

    def greentheme():
        text.config(background="pale green", foreground="dark green",
                    insertbackground="dark green")

    def bluetheme():
        text.config(background="light blue", foreground="dark blue",
                    insertbackground="blue")

(text is the name of the text widget)
So i want to create a function that makes a random one of these functions run whenever the application is started.
in other words: I want a function that is executed when the application starts, the function will choose from random.choice, a function and execute that function:

    full = (redtheme, greentheme, bluetheme)
    selected = random.choice(full)
    # here, it could be text.config(full)?? or what?

now, how do i make it so that one of the 3 functions is executed whenever tha application starts
