class object using widget

[asit]

from Tkinter import * # get widget classes
from tkMessageBox import askokcancel # get canned std dialog

class Quitter(Frame): # subclass our GUI
def __init__(self, parent=None): # constructor method
Frame.__init__(self, parent)
self.pack()
widget = Button(self, text='Quit', command=self.quit)
widget.pack(side=LEFT)
def quit(self):
ans = askokcancel('Verify exit', "Really quit?")
if ans: Frame.quit(self)

if __name__ == '__main__': Quitter().mainloop()

In the above program, why the error comes ??

This example works.
I only used carriage return and spacebar for
formatting.

You are using '\xc2' whatever that
represents, I'm not sure. But if you
carriage return at the end of each line then
delete until the next line comes to the
cursor then use only space bar and carriage
return (Enter) to format you will fix it.
Or copy below and paste into your file.
