That is how the data is printed - those things are not part of the
data. To generate HTML you will have to iterate over the result set
and create the needed markup. E.g.:

html = "<table>"
for row in myresult:
    html += "<tr>"
    for item in row:
        html += "<td>%s</td>" % item
    html += "</tr>"
html += "</table>"
