  using python get friend timeline in twitter. following tools should be used:

  python-twitter

  python-simplejson

  first install python-simplejson, if in ubuntu, just using command as follows

  $apt-get install python-simplejson

  then, downloading python-twitter , unpackage it. then using command

    $ python setup.py build
    $ python setup.py install

  then, open python.

  >>> import twitter

  >>> api = twitter.Api(“username”, “passworld”)

  >>> posts = api.GetFriendsTimeline(‘username’)

  >>> print [post.text in post as posts ];

  for the file, the script should be liked:
  
import twitter
class mytwitter():

  def __init__(self):
  self._config = None

  def main():
  api = twitter.Api('username', 'passworld')
  posts = api.GetFriendsTimeline('username')
  for post in posts:
  print post.text.encode('utf-8')

  if __name__ == "__main__":
main()

  first look kubuntu.

  the most bugs of KDE have been fixed. the wifi mod has been improved. the package library adds many new software, like monodevelop2 firefox 3.1 and 3.5, kooldock, etc. but I didn’t see katapult.
