The best definition of simple I've found is "one that takes the least cognitive load to use/comprehend." With programming it's actually hugely complicated, because are you trying to lower the mental effort to read, or the mental effort to write? a + b is simple to write because it reminds you of high school mathematics. However, I'd argue from operator import add, mul def square(x): return mul(x, x) def sum_squares(x, y): return add(square(x), square(y)) result = sum_squares(5, 12) Is an excellent way for newer programmers to read code, and learn what is happening.
