Thanks Roy. A little closer to a solution. I'm still processing how to
step forward, but this is a good start:
>>> string = 'abc 123 def 456 ghi 789'
>>> rePatt = re.compile('\s\d+\s')
>>> foundGroup = rePatt.findall(string)
>>> newstring = ' INSERT '.join(foundGroup)
>>> print newstring
123 INSERT 456
What I really want to do is return the full string, not just the
matches -- concatenated around the ' INSERT ' string.
