Adding sender name to email

[gillespie.amanda at gmail.com]

How do I add a Sender name to the emails sent by the following script:

def createhtmlmail (html, text, subject):
      	"""Create a mime-message that will render HTML in popular
	   MUAs, text in better ones"""
	import MimeWriter
	import mimetools
	import cStringIO

	out = cStringIO.StringIO() # output buffer for our message
	htmlin = cStringIO.StringIO(html)
 	txtin = cStringIO.StringIO(text)

	writer = MimeWriter.MimeWriter(out)
	# set up some basic headers... we put subject here
	# because smtplib.sendmail expects it to be in the
	# message body
	#
	writer.addheader("Subject", subject)
	writer.addheader("MIME-Version", "1.0")
	#
	# start the multipart section of the message
	# multipart/alternative seems to work better
	# on some MUAs than multipart/mixed
	#
	writer.startmultipartbody("alternative")
	writer.flushheaders()
	#
	# the plain text section
	#
	subpart = writer.nextpart()
	subpart.addheader("Content-Transfer-Encoding", "quoted-printable")
	pout = subpart.startbody("text/plain", [("charset", 'us-ascii')])
	mimetools.encode(txtin, pout, 'quoted-printable')
	txtin.close()
	#
	# start the html subpart of the message
	#
	subpart = writer.nextpart()
	subpart.addheader("Content-Transfer-Encoding", "quoted-printable")
	#
	# returns us a file-ish object we can write to
	#
	pout = subpart.startbody("text/html", [("charset", 'us-ascii')])
	mimetools.encode(htmlin, pout, 'quoted-printable')
	htmlin.close()
	#
	# Now that we're done, close our writer and
	# return the message body
	#
	writer.lastpart()
	msg = out.getvalue()
	out.close()
	return msg
