I've been away from alchemy for a while, but got back into it yesterday - glad that I did. I am going to spend a minimum of two hours per day on it, until I feel a lot more comfortable. Right now, working through the intro/Kaggle stuff, which is really helping me with putting together my convoluted knowledge of python. I've used it in spot-situations with a lot of hunt/peck/stack-overflow for point solution solves. It's easy to read. But going through the intro stuff in Kaggle has actually been really helpful as it ties all the fundamentals together. Good recommendation to use it.
