I use Python on a daily basis, for about three years now. I can't remember ever having a problem or a gripe with the language or the standard library. In all those years it has served me well and it continues to do so - I also have no hurry migrating to Python 3.

I miss nothing in Python, it's all there, source code, excellent documentation and website, very nice and clean language, superb datastructures, a fairly complete stdlib and a fantastic community of people around it.

Is Python complete? It seems that for me it is indeed. Others may still miss things. But I perceive the 'stagnant design' mentioned in another post as an advantage: it provides stability.
