Or if you don't like Lisp, use a class...
I'll make it slightly more generic.

 >>> class Tag:
...     def __init__(self, tag):
...             self.tag =3D tag
...     def __call__(self, text):
...             return "<%s>%s</%s>" % (self.tag, text, self.tag)
...
 >>> H1 =3D Tag('h1')
 >>> HTML =3D Tag('html')
 >>> print HTML(H1('Hello')+'\nHow are you.\n'+H1('Goodbye')+'\nSee you=20
later.\n')
<html><h1>Hello</h1>
How are you.
<h1>Goodbye</h1>
See you later.
</html>
