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?
