nntplib.NNTP.login()

NNTP.login(user=None, password=None, usenetrc=True)

Send AUTHINFO commands with the user name and password. If user and password are None and usenetrc is true, credentials from ~/.netrc will be used if possible.

Unless intentionally delayed, login is normally performed during the NNTP object initialization and separately calling this function is unnecessary. To force authentication to be delayed, you must not set user or password when creating the object, and must set usenetrc to False.
