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

Just to make the answer of Nae a little bit more elaborate, here is a full blown example which includes the possibility to pass a variable to the callback which contains different values for each button:

import tkinter as tk
    
def callback(text):
    print(text)

top = tk.Tk()
Texts=["text1", "text2", "text3"]
Buttons=[]

for i, z in enumerate(Texts):
    Buttons.append(tk.Button(top, text=z, command= lambda ztemp=z : callback(ztemp)))
    Buttons[i].pack(side=tk.LEFT, padx=5)

top.mainloop()

By defining a temporary variable ztemp, the value of that variable gets fixed at the moment when the button is defined.
