Well, depending on whether "row" is a tuple or a list, you can do 
either

   row[2] = row[2].strftime(...)  # if it's a list
   # the assignment will fail if it's a tuple

or you can just iterate over a predefined list/tuple:

   for row in dataset:
     print ("<tr>")
     for item in (row[0], row[1], row[2].strftime(...)):
       print ("<td>%s</td" % item)
     print ("</tr>")

Though I think I'd make it a bit clearer by naming the fields:

   for host, hits, dt in dataset:
     print ("<tr>")
     for item in (host, hits, dt.strftime(...)):
       print ("<td>%s</td>" % item)
     print ("</tr>")

Or perhaps even just

     print ("".join("<td>%s</td>" % item
       for item in (host, hits, dt.strftime(...))
       )

Whichever you prefer.  I think I'm partial to the 2nd-from-last 
version, especially as the list of fields may grow.
