How to change Tkinter label text on button press

Question

I have this code, and its meant to change the text of the Instruction label when the item button is pressed. It doesn\'t for some reason, and I\'m not entirely

Answer 1

You can make message a StringVar to make callback.

message = tkinter.StringVar()

message.set('Not pressed.')

You need to set message to be a textvariable for Instruction:

Instruction = tkinter.Label(Tk, textvariable=message, font='size, 20').pack()

and then

def press():
    message.set('Button Pressed')
