Example: >>> from nntplib import NNTP >>> s = NNTP('news') >>> resp, count, first, last, name = s.group('comp.lang.python') >>> print 'Group', name, 'has', count, 'articles, range', first, 'to', last Group comp.lang.python has 51 articles, range 5770 to 5821 >>> resp, subs = s.xhdr('subject', first + '-' + last) >>> resp = s.quit() >>> Here 'resp' is the server response line. Error responses are turned into exceptions. To post an article from a file: >>> f = open(filename, 'r') # file containing article, including header >>> resp = s.post(f) >>> For descriptions of all methods, read the comments in the code below. Note that all arguments and return values representing article numbers are strings, not numbers, since they are rarely used for calculations. iNtNNTPtNNTPReplyErrortNNTPTemporaryErrortNNTPPermanentErrortNNTPProtocolErrort NNTPDataErrort error_replyt error_tempt error_permt error_protot error_datat NNTPErrorcBseZdZdZRS(s%Base class for all nntplib exceptionscGsBtj||y|d|_Wntk r=d|_nXdS(NisNo response given(t Exceptiont__init__tresponset IndexError(tselftargs((s/usr/lib/python2.7/nntplib.pyR +s  (t__name__t __module__t__doc__R (((s/usr/lib/python2.7/nntplib.pyR )scBseZdZRS(sUnexpected [123]xx reply(RRR(((s/usr/lib/python2.7/nntplib.pyR2scBseZdZRS(s 4xx errors(RRR(((s/usr/lib/python2.7/nntplib.pyR6scBseZdZRS(s 5xx errors(RRR(((s/usr/lib/python2.7/nntplib.pyR:scBseZdZRS(s"Response does not begin with [1-5](RRR(((s/usr/lib/python2.7/nntplib.pyR>scBseZdZRS(sError in response data(RRR(((s/usr/lib/python2.7/nntplib.pyRBsiwt100t215t220t221t222t224t230t231t282s cBsyeZed#d#d#edZdZdZeZdZ dZ dZ dZ d#dZ dZd#d Zd#d Zd#d Zd#d Zd ZdZdZd#dZdZdZdZdZdZd#dZdZd#dZdZdZ d#dZ!d#dZ"d#dZ#dZ$dZ%d Z&d!Z'd"Z(RS($c Cs||_||_tj||f|_|jjd|_d|_|j|_ d}|ry|j d|_ Wqt k rqt k r}|r|j d dkrd}qqXnyX|r| rddl} | j} | j|} | r| d}| d }qnWntk r2nX|r|j d |} | d d kr|sqt| q|j d |} | d d krt | qn|ry|j d|_ Wqt k rqXqndS(smInitialize an instance.
