[SOLVED] How to use nntplib module?

How to use nntplib module?

When I use first example in Python's nntplib module documentation, there are some errors.

>>> from nntplib import NNTP
>>> s = NNTP('news.gmane.org')
>>> resp, count, first, last, name = s.group('gmane.comp.python.committers')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Python27\lib\nntplib.py", line 354, in group
    resp = self.shortcmd('GROUP ' + name)
  File "C:\Python27\lib\nntplib.py", line 268, in shortcmd
    return self.getresp()
  File "C:\Python27\lib\nntplib.py", line 223, in getresp
    resp = self.getline()
  File "C:\Python27\lib\nntplib.py", line 215, in getline
    if not line: raise EOFError
EOFError

Why does this happen?

Solution

Try s = NNTP('news.gmane.org', readermode=True)

As mentioned in the docs:

If the optional flag readermode is true, then a mode reader command is sent before authentication is performed. Reader mode 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.
