It wasn't a matter of copying. I had experimented with the code and found a 
note that suggested using Tk, and another way of getting the job. It didn't 
work. I missed removing it (Tk).

Here's the segment the author singled out:

v = StringVar()
e = Entry(master, textvariable=v)
e.pack()

v.set("a default value")
s = v.get()
