I actually don't like forced readability like the python whitespace as I think it stifles creativity, and the only way it makes code better to read is by forced formatting (the forced white space) while your code can still have hard to read logical loops, blocks, variables.

In a way, it stiffles creativity just for a small gain of formating/readibility.

Plus, with modern IDEs it is very simple to format the code the way you want. In eclipse you have RightClick -> Source -> Format then viola, your code looks the way you want.

Having worked with both python and java, I have enountered more hard to read code in python than in java, (maybe this is due to the superior tools/IDEs in java).

As for ada, i thought it was a great language to start learning programming. Exceptions are verbose, and it is an easy language to pick up, as it looks a lot like Pascal. I learned it my freshman year, but I never used it in a production capacity and I wouldn't consider doing anything serious with it right now.
