[Baypiggies] processing multiple lists in step

[Daryl Spitzer]

See the zip() built-in function:
http://docs.python.org/library/functions.html#zip.  I note the
documentation says it returns a list of tuples, which is (I assume)
why Charles writes "for in memory objects".

For an iterator, see itertools.izip() or itertools.izip_longest():
http://docs.python.org/library/itertools.html#itertools.izip.
