How to pass arguments to a Button command in Tkinter?

Question

Suppose I have the following Button made with Tkinter in Python:

import Tkinter as Tk
win = Tk.Toplevel()
frame = Tk.Frame(master=win).grid(row=         


        

Answer 1

You need to use lambda:

button = Tk.Button(master=frame, text='press', command=lambda: action(someNumber))
