How to Disable/Enable Tkinter Button in Python
In this tutorial, we are going to see how to disable/enable Tkinter button in Python.
A Tkinter button has three states: active, normal, disabled.
You set the state option to “disabled” to grey out the button and make it insensitive. The button has the value “active” when the mouse is on it and the default value is “normal”.

btn2 = Button(root, text = "Button 2")
btn2.pack(side = RIGHT)
root.mainloop()

root = Tk()
root.geometry('300x100')
#Button 1: not clickable
btn1 = Button(root, text = "Button 1", state = DISABLED)
btn1.pack(side = LEFT)
#Bouton 2 : clickable
btn2 = Button(root, text="Enable/Disable Btn 1", command=changeState)
