Another way, which has not yet been mentioned but which I like much,
is the cStringIO module. You can write to a string as if it is a
file:

  0 >>> import cStringIO
  1 >>> mystr = cStringIO.StringIO()
  2 >>> mystr.write("<html")
  3 >>> mystr.write("<body>")
  4 >>> mystr.write("<h1>Header</h1>")
  5 >>> mystr.write("<p>Hello, world!</p>")
  6 >>> mystr.write("</body></html>")
 10 >>> mystr.getvalue()
'<html<body><h1>Header</h1><p>Hello, world!</p></body></html>'

The cStringIO module is documented at:

http://www.python.org/dev/doc/devel/lib/module-StringIO.html

cStringIO is a faster C implementation with the same API.
