Although the itertools is probably the way to go here, I've used the  
following construct, especially in two-player games.  I like the  
readability of it:

value='Even'
other_value='Odd'
for i, (id,name) in enumerate(result):
     stringBuffer.write('''
     <tr class="%s">
         <td>%d</td>
         <td>%s</td>
     </tr>
     ''' % (value,id,name)


     value,other_value=other_value,value   # swap the value
