Can I have any highlight kind of things using Python 2.7? Say when my script clicking on the submit button,feeding data into the text field or selecting values from the drop-down field, just to highlight on that element to make sure to the script runner that his/her script doing what he/she wants.
EDIT
I am using selenium-webdriver with python to automate some web based work on a third party application.
Thanks
[NOTE: I'm leaving this answer for historical purposes but readers should note that the original question has changed from concerning itself with Python to concerning itself with Selenium]
Assuming you're talking about a browser based application being served from a Python back-end server (and it's just a guess since there's no information in your post):
If you are constructing a response in your Python back-end, wrap the stuff that you want to highlight in a <span> tag and set a class on the span tag.  Then, in your CSS define that class with whatever highlighting properties you want to use.
However, if you want to accomplish this highlighting in an already-loaded browser page without generating new HTML on the back end and returning that to the browser, then Python (on the server) has no knowledge of or ability to affect the web page in browser.  You must accomplish this using Javascript or a Javascript library or framework in the browser.
Can selenium be used to highlight sections of a web page?
