Introduction to Computation and Programming Using Python Quotes

“The key to using abstraction effectively in programming is finding a notion of relevance that is appropriate for both the builder of an abstraction and the potential clients of the abstraction. That is the true art of programming.”
― John V. Guttag, Introduction to Computation and Programming Using Python

“A computer does two things, and two things only: it performs calculations and it remembers the results of those calculations.”
― John V. Guttag, Introduction to Computation and Programming Using Python

“prints L1 = [[2, 3]] L2 = [[2, 3]] because both L1 and L2 contain the object that was bound to L in the first assignment statement.”
― John V. Guttag, Introduction to Computation and Programming Using Python: With Application to Computational Modeling and Understanding Data

“Texas sharpshooter fallacy: Imagine that you are driving down a country road in Texas. You see a barn that has six targets painted on it, and a bullet hole at the very center of each target. “Yes sir,” says the owner of the barn, “I never miss.” “That’s right,” says his spouse, “there ain’t a man in the state of Texas who’s more accurate with a paint brush.” Got it? He fired the six shots, and then painted the targets around them.”
