Hi

I am not an expert but one recent development is dynamic languages such as Python can now be interpreted and run inside browsers, making it possible to do the below kind of stuff as well as execution with no need of servers.

One such example seems to be http://pythonlearn.com/pythonauto/index.php which uses http://www.skulpt.org/

Yes, Skulpt features an ingenious JavaScript interpreter of the Python language. The simple SDK, which requires Python to run, lets developers add new features and tests to the JavaScript interpreter. In end user mode, you can write Python interactively without having even Python installed, and without Internet access (though there's a high probability you have both).
