Tkinter. Create multiple buttons with “different” command function

Question

first of all, sorry for the title, I couldn\'t find a better one.

The following code is a minimalized version of a problem I have in my Python program (I am a newbie btw

Answer 1

Use default parameter to avoid late-binding issue (Otherwise i is bound when the lambda function is called, not when it is created):

def start():
    buttons = []
    win = Tkinter.Tk()
    for i in range(5):
        b = Tkinter.Button(win, height=10, width=100, command=lambda i=i: onClick(i))
        b.pack()
        buttons.append(b)
