Makes user change Tkinter button if clicked?

Question

I have this code:

def userChoice():
    text = "Clicked"


row1 = Button(root, text=" ", command = "userChoice")
row1.config(height="6", width="10")
row1.grid(row=0, column=0)

I want to make it so that when the user clicks the button the text is changed. I am not sure how I would do this I ran this code and when the button is clicked nothing happens? I know this is a very simple question but just cannot figure out how to do it. I have been trying for the pas hour or so.

You can use row1["text"] to set new value:

from Tkinter import *

root = Tk()

def userChoice():
    row1["text"] = "CLICKED!"


row1 = Button(root, text=" ", command = userChoice)
row1.config(height="6", width="10")
row1.grid(row=0, column=0)

mainloop()
