But why do that?  Clumsy, as you say.

eval??  I must be misunderstanding what your problem is.  You do
realise that variable names in a program don't have to match the names
you put in your markup, right?

...or in any language!  If I understand your problem correctly, you
just iterate over a range of integers.

print "<form>"

nr_people = 2

for i in range(nr_people):
    print "  <td>"
    print '    <input name="name%d">' % i
    print '    <input name="phone%d">' % i
    print "  </td>"

print "</form>"

Why *would* you expect to find an example that exactly matches your
particular problem?
