Or use 'help' (which is build on top of inspect):
  >>> from smtplib import SMTP
  >>> help(SMTP)
Help on class SMTP in module smtplib:

class SMTP
  |  This class manages a connection to an SMTP or ESMTP server.
  |  SMTP Objects:
  |      SMTP objects have the following attributes:
  |          helo_resp
  |              This is the message given by the server in response to the
  |              most recent HELO command.
etc.
