[Zope] iterating over result sets in python

[Peter Bengtsson]

That's easy.

prev_date = None
for record in recordset:
    if prev_date is None:
        prev_date = record.mydate
        print "first date: %s" % record.mydate
    elif (prev_date + 30) > record.mydate:
        print "%s days since previous date" % (record.mydate - prev_date)
