I installed python packages through `pip`:

#+begin_src shell
pip install deluge-client
#+end_src

If you want to test those src blocks, you also need to make sure Deluge 
installed and daemon started.

And use `deluge-client` like this:

#+NAME: deluge-daemon-username
#+begin_src shell
cat ~/.config/deluge/auth | cut -d ":" -f 1
#+end_src

#+RESULTS: deluge-daemon-username
: localclient

#+NAME: deluge-daemon-password
#+begin_src shell
cat ~/.config/deluge/auth | cut -d ":" -f 2
#+end_src

#+RESULTS: deluge-daemon-password
: 9b83ceded9ac08cc5c7403b093115874a6086958

#+begin_src python :noweb yes :results list
from deluge_client import DelugeRPCClient

client = DelugeRPCClient('127.0.0.1', 58846, username, password)
client.connect()
client.connected # True
client.call('core.get_torrents_status', {}, ['name'])
#=> {'79816060ea56d56f2a2148cd45705511079f9bca': {'name': 
'TPB.AFK.2013.720p.h264-SimonKlose'}}
#+end_src


But got error:

```
