I'd been looking forward to this particular lesson all semester, but when I got home and copied a sample program from my textbook verbatim, IDLE does nothing. No error, no nothing. Any ideas? Here  is the code from my program. I'm not sure if this is appropriate, but suggestions are helpful.

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.)
