How can I execute a Python script from Javascript?
Probably a late reply but a possible solution is to make your python script act as a server and let the browser plugin interact with it.
I have written a module in python which performs some function.
I then created a Google Chrome extension which makes use of JSON and javascript.
Now when I click on the extension I want it to execute the python program which is stored on my hard disk and display the output on the browser again. 
Is there a way in which I can do this??
