Python Tkinter button callback

button, callback, python, tkinter

Solution

Blender's answer is a clever solution but in case you get thrown off by the function abstraction, here is another possible way to do it. It really just creates a mapping, saved in `buttons`, from `Button` widgets to their proper numbers.

import Tkinter as tk
root = tk.Tk()

def myfunction(event):
    print buttons[event.widget]

buttons = {}
for i in range(10):
    b = tk.Button(root, text='button' + str(i))
    buttons[b] = i # save button, index as key-value pair
    b.bind("<Button-1>", myfunction)
    b.place(x=10,y=(10+(25*i)))
root.mainloop()

Problem

I am trying to print out the button number when i click each buttons that are created by for loop. The following is what i have tried. ``` import Tkinter as tk root=tk.Tk() def myfunction(a): print a for i in range(10): tk.Button(root,text='button'+str(i),command=lambda:myfunction(i)).place(x=10,y=(10+(25*i))) root.mainloop() ``` But instead of printing out each button number, it actually giving me the last button number everytime. Is there anything i can do so that when i click button 1, it will print 1,2 for 2 ,and so on?
