How to Pass Arguments to a Tkinter Button's Command Function?

How to Send Arguments to a Tkinter Button Command

Question:

Consider the following Tkinter button:

import Tkinter as Tk
win = Tk.Toplevel()
frame = Tk.Frame(master=win).grid(row=1, column=1)
button = Tk.Button(master=frame, text='press', command=action)

How can you pass arguments to the action method when the button is pressed?

Explanation:

The provided code calls the action method immediately when the button is created, rendering the button ineffective.

Solution:

To pass arguments, you can use a lambda function:

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

The lambda function binds the argument to the command without requiring an explicit wrapper method or modifying the original action.
