I want to take input from the webpage, parse the data submitted using python or tcl and start the script execution based on the inputs given. 
Please suggest me a solution, how it can be done. 
I am not sure whether some web server need to be started for this.
Thanks in Advance.

Surya, 
you should have a look at the ncgi and htmlparse packages in tcllib to extract the information you need.
