poop? Seriously? You aren’t serious about that copying, right?
Your code seems to be missing a lot of important stuff. You don’t
inherit from tkinter.Frame. Compare your program to the sample “Hello
world!” program:
http://docs.python.org/2/library/tkinter.html#a-simple-hello-world-program
— unfortunately, I am not a fan and I am not knowledgeable about
tkinter, but I can see a lot of stuff is missing.
Please try fixing it and running it _outside of IDLE_, which is also
built in Tk. This may cause problems (but don’t worry, the code you
pasted doesn’t work anyways.)
