I just got this book ~2 weeks ago and am using it in conjunction with udacity's course. Python Machine Learning (PML) is more low-level, math intensive, and hands on than udacity and other resources I'm using.

Thus far Udacity's course fits your explanation of using sklearn docs, tweaking inputs, etc. while PML provides a technical explanation of weighting with perceptrons and then you hand-write a perceptron learning algorithm.
