I just had a quick look at the documentation. It looks like you should
re-read it.
http://docs.python.org/py3k/library/nntplib.html#nntplib.NNTP.xhdr
xhdr returns a whole list. It looks like you'd need something like
resp, subjects = server.xhdr('subject', '{0}-{1}'.format(first, last))
for sub in subjects:
print (sub)
you should also have another close look at the documentation of xover:
http://docs.python.org/py3k/library/nntplib.html#nntplib.NNTP.xover
and then maybe write something like this:
resp, items = server.xover(first, last)
subjects = (info[1] for info in items)
for s in subjects:
print (s)
Have fun,
Thomas
PS: my untested code here was sketched up with Python 3.x in mind. You
might have to change one or two things for it to work on older versions.
