How to send the text pasted in a textbox of a html webpage to the application written in python in the harddisk?
Have you tried PyQt4 which has this ability built-in? You can do what you're asking in about ten LOC.
I have a application running in python, i want to send the input taken from the text box of the webpage and send it as input to the application and once again the output of the application which is in text format back to the result page on web. 
thanks a lot for your time :) :)
