A 'Box' Function

Hey guys.

I should warn you, first off, that I'm relatively new to Python.
Basically, what I'm trying to do is create a word-wrapping function
with the added complication that it add a character at the beginning
and end of each line, so that it encloses the text in a sort of 'box':

----------------
| Like this |
----------------

The word-wrapping function I'm working with is similar to the one given
here:
http://aspn.activestate.com/ASPN/Coo.../Recipe/148061

def wrap(text, width):
return reduce(lambda line, word, width=width: '%s%s%s' %
(line,
' \n'[(len(line)-line.rfind('\n' )-1
+ len(word.split( '\n',1)[0]
) >= width)],
word),
text.split(' ')
)

Does anyone have any ideas on how it could be modified? Am I
approaching it the right way? Thanks a bunch!

Mike

I have never used this, but it might help you
import textwrap
dir(textwrap)

['TextWrapper', '__all__', '__builtins__', '__doc__', '__file__',
'__name__', '__revision__', '_whitespace', 'dedent', 'fill', 're',
'string', 'wrap']

Rather than rewriting wrap(), I would suggest wrapping it with a new
function, wrap_box(), that adds the header, line endings and trailer to
the lines returned from wrap().
