Use of node-python to execute python scripts from web application hosted under python?

Question

I've written python scripts for some numerical analysis topics and so I want to plot them in a nice way using any Java Script library.

So, I got to know about python-node and they show some brief doc info at that site:

var python = require('node-python');
var os = python.import('os');

// nodejs stuff
var path = require('path');

assert(os.path.basename(os.getcwd()) == path.basename(process.cwd()))

However, how could I start to actually do python, import python libraries, run python scripts, etc?

That example show how to use import and call functions.

Try following:

var python = require('node-python');
var script = python.import('your_script_module_name');

script.your_function(argument1, argument2)

So I could even do more than one `script = python.import('your_script_module_name');` lines to keep coding, right? – diegoaguilar Feb 09 '14 at 05:19
I got module in same folder and I get: `Error: No module named python.taylorsum...` – diegoaguilar Feb 09 '14 at 05:56
@diegoaguilar, Did you set `PYTHONPATH=.` as I did in the screencast? – falsetru Feb 09 '14 at 05:57
I did, yes, being `.` the folder from where such an *`app.js`* is being started – diegoaguilar Feb 09 '14 at 06:01
@diegoaguilar, Do you have a `python` directory in the same directory? If so, does `python` directory is a package (having `__init__.py`)? – falsetru Feb 09 '14 at 06:04
No, I've got any python named directory :/ – diegoaguilar Feb 09 '14 at 06:09
@diegoaguilar, Then, why do you try import `python.taylorsum` instead of `taylorsum` ? – falsetru Feb 09 '14 at 06:10
Did, later moved them to same directory where PYTHONPATH is being set. Also removed python. prefix at import – diegoaguilar Feb 09 '14 at 06:13
