- RFC 977: Network News Transfer Protocol
- RFC 2980: Common NNTP Extensions
- RFC 3977: Network News Transfer Protocol (version 2)
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', '{0}-{1}'.format(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, 'rb') # 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.

date object is passed, the time is assumed to be midnight (00h00).
The returned representation depends on the legacy flag:
* if legacy is False (the default):
date has the YYYYMMDD format and time the HHMMSS format
* if legacy is True:
date has the YYMMDD format and time the HHMMSS format.
RFC 3977 compliant servers should understand both formats; therefore,
legacy is only needed when talking to old servers.

- readermode: if true, send 'mode reader' command after

- usenetrc: allow loading username and password from ~/.netrc file
if not specified explicitly
- timeout: timeout (in seconds) used for socket connections
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.
