Style (1) is generally to be preferred.  "from X import *" is almost
universally shunned because it fills your namespace in ways that you
can't really control.  There may be a few good nice ways to use 'from'
(one is getting a single module from a package), but in general if you
were to forget the existence of the 'from' statement, in favour of
using only the 'import' statement, your Python code wouldn't suffer.
