It's a token, a static value added to the template to indicate where
additional data will be added.
So $ROW$ in this section:
<table>
<tr><th>key<td><input type=text name=key value="%(key)s">
$ROWS$
> </table>
Will be replaced by whatever rowshtml contains at this point:
replyhtml = replyhtml.replace('$ROWS$', rowshtml)
Of note: the template section above has opening tags for <tr>, <th> and
<td> but no closing ones. It's not valid html.
Also I don't think this is doing what you think it is:
> rowhtml = '<tr><th>%s<td><input type=text name=%s value="%%(%s)s">\n'
> rowshtml = ''

After the first fieldname ('name' in this case), the token $ROWS$ will
be replaced by the string :
'<tr><th>name<td><input type=text name=name value="%%(name)s">\n'.
On the second iteration of the loop, when fieldname is 'age', rowshtml
will equal:
'<tr><th>name<td><input type=text name=name
value="%%(name)s">\n<tr><th>age<td><input type=text name=age
value="%%(age)s">\n'
...but nothing will happen with it as $ROWS$ has already been replaced
during the first time through the loop. Either the `replyhtml = ...`
line is mis-indented or the code is terribly broken.
Unless this is for homework, I highly recommend just using one of the
many templating libraries that exist for Python, such as Jinja2.
