ob-python noweb and :var reference error

ob-python noweb and :var reference error

[stardiviner]

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:

```

Shouldn't this be:

  client = DelugeRPCClient('127.0.0.1', 58846, <<deluge-daemon-username>>, <<deluge-daemon-password>>)

Untested.

If I use that noweb reference, then I got this error:

 >  File "<stdin>", line 8
 >    client = DelugeRPCClient('127.0.0.1', 58846, cat 
~/.config/deluge/auth | cut -d ":" -f 1, cat ~/.config/deluge/auth | cut 
-d ":" -f 2)
                                                      ^
SyntaxError: invalid syntax

This is because the <<deluge-daemon-username>> output is not a string in 
Python src block.

I also tried to specify `:results` to `value`, `output` and `raw` in 
`deluge-daemon-password` etc. But none of them works.

My bad. Try 

  <<deluge-daemon-username()>>

This seems fixed not string problem.

But I got new error:

```

    File "<stdin>", line 9
     client = DelugeRPCClient('127.0.0.1', 58846, , 
9b83ceded9ac08cc5c7403b093115874a6086958
          ^
SyntaxError: invalid syntax

```

I execute src block:

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

#+RESULTS: deluge-daemon-username
: localclient

correctly.

But in the python src block, the result is not inserted.

I noticed the echo-area message, the `deluge-daemon-username` src block 
execute is correct.

I will try to edebug on this.
