Thanks Matt.

I have my date-matching re (for incidences of 3/31/03 or 12/3/2003, for example):

s = '3/31/03 some text 12/3/2003 some more text.'
p = re.compile('\d+/\d+/\d+')
s = p.sub('\n\n', s)

Now, I want to precede each match with two newlines. How do I do this, instead 
of replacing each match like above?
