How do I call upon Tkinter labels defined in a different function?

I am making a simple little clicker game using Python. This is currently what I have:

from tkinter import *

x = [0]
y = [1]

class Game:
    def __init__(self, master):
        master.title('Game')

        Amount = Label(master,text=x[0])
        Amount.pack()

        Butt = Button(master,text='Press!',command=self.click)
        Butt.pack()

    def click(self):
        x[0] = x[0] + y[0]
        Amount.config(root,text=x[0])
        print(x[0])

root = Tk()
root.geometry('200x50')
game = Game(root)
root.mainloop()

When I run this, it tells me that 'Amount' is not defined within the click function. I know this is because it's defined in a different function. I want to know how to make it so the click function recognizes 'Amount'.

You should either define your amount as data member(each instance has his value) or static member(same value withing all classes instances).

I would go with data member.

In order to use it as a data member you should use self.Amount.

So, this is what you need:

from tkinter import *

x = [0]
y = [1]

class Game:
    def __init__(self, master):
        master.title('Game')

        self.Amount = Label(master,text=x[0])
        self.Amount.pack()

        Butt = Button(master,text='Press!',command=self.click)
        Butt.pack()

    def click(self):
        x[0] = x[0] + y[0]
        self.Amount.config(text=x[0])
        print(x[0])

root = Tk()
root.geometry('200x50')
game = Game(root)
root.mainloop()

self is shared among your class methods, so you can access the Amount variable through it.
