Query: Possibly the perfect intro to CompSci Textbook

As a young professional programmer who has never taken a CompSci class of any kind I have quite a fondness for intro books as they tend to 'fill in the gaps'/ stroke my ego. Thus I've read a LOT of intro to CompSci books most of have been rather awful. This book however, is simply not one of them.The books small size, approachable language, excellent examples and Socratic pedagogical orientation in addition to the authors seemingly effortless lucidity is enough to drop any jaw.If we were to be critical, we should perhaps ask the author to show greater concern for data casting. Python is a loosely casted language and thus this important concept takes a back seat.Nonetheless for the books scope (a first course in Computer Science) I can not imagine and have yet to read a better primmer.
