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

I personally prefer to use lambdas in such a scenario, because imo it's clearer and simpler and also doesn't force you to write lots of wrapper methods if you don't have control over the called method, but that's certainly a matter of taste.

That's how you'd do it with a lambda (note there's also some implementation of currying in the functional module, so you can use that too):

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