When I first picked up Python, I typed in a couple of examples from
Grayson's book.  I would always say:

import Tkinter
tk = Tkinter
root = tk.Tk()
# etc

I tacked on a 'tk.' in front of tk calls.  I wanted to know which function
came from tk and which came from the standard python library etc. 

For what it's worth, I'd like to say that I'm happy that from ... import..*
is discouraged and if it disappeard from the language completely, I wouldn't
miss it.  Only slightly related is the fact anything that looks like
Pascal's 'with' would be completely wasted on me. :-)   I'd rather prepend
class name.  Explicit is better than implicit, right?
