In python you almost never want to use a counting loop.  The above is better
written as:

for piece in result:
    text = text + '<td align="center" valign="top"> + piece + '</td>'

the string append is slow, so this:

table_entries = []
for piece in result:
    tables_entries.append('<td align="center" valign="top">%s</td>' % piece)

text = string.join(tables_entries, '')

will work better still.  Although you may find the first version more readable.
