Question

I have modified http://fivefilters.org/term-extraction/ this project so that:

Given input (https://gist.github.com/4426264) of text the python script term-extraction.py outputs keywords in json format and sends via POST the json to a php file
term-extraction.py -> echo.php

link to term-extraction.py https://gist.github.com/4426181
link to echo.php https://gist.github.com/4426193

here is the json output given by the php script: https://gist.github.com/4426197
here is the output of term-extraction.py : http://jsfiddle.net/Bw7UX/

here is the desired array output that I would like to be passed into php: https://gist.github.com/4426208

So, my problem essentially is that:

Array
(
    [json] => None
)

I would like the php array to have the value of all the keywords from the python script, like this link: https://gist.github.com/4426208

array(42) {
  [0]=>
  string(10) "rajaratnam"
  [1]=>
  string(5) "court"
  [2]=>
  string(14) "district court"
...
[41]=>
string(6) "appeal"
}

I think my problem may be with line 69 thru 78 of term-extraction.py and specifically this line:

mydata=[('json',  self.response.out.write(json.dumps(list, indent=0)))] #trying to create an 

Thanks in advance for your replies, I am very new to python so I appreciate the patience.

edit: This is the output when the script is run. I do not get why the json is being output from they python script but it is not in the PHP array properly.
`
START echo.php

NULL

echoing post json:
POST ITEMS:
NO POST ITEMS
Array

)
END echo.php

Seems that self.response.out.write function returns None. I think on line 69 you should have:

mydata = json.dumps({'json': list}, indent=0)
