Difference between python selenium webdriver and just selenium?
Which one should I use?
It depends on your goals. If you need to automate some testcases, it's okay to use both of them. But if you are to start some big process, for example testing automation in your company, I would suggest you to use Webdriver. It would give you more portability and it is more modern. By the way, I am not sure, that Selenium RC is to be developed further.
