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.

- host: hostname to connect to
- port: port to connect to (default the standard NNTP port)
- user: username to authenticate with
- password: password to use with username
- readermode: if true, send 'mode reader' command after
connecting.
readermode is sometimes necessary if you are connecting to an
NNTP server on the local machine and intend to call
reader-specific commands, such as `group'. If you get
unexpected NNTPPermanentErrors, you might need to set
readermode.

This elides the response code from the server, since it can
only be '215' or '285' (for xgtitle) anyway. If the response
code is needed, use the 'descriptions' method.

it check whether the group actually exists.i t i N( t descriptionsRD ( R R] R8 t lines( ( s /usr/lib64/python2.7/nntplib.pyt description4 s
