Python's list comprehensions are close to set notation in math. Here's Python: [2*x for x in range(n + 1) if x <= 100] Here's set notation: {2*x | x in 0..n, x <= 100} So it reads pretty easily for those of us used to set notation. Haskell is even more similar to set notation: [2*x | x <- [0..n], x <= 100]
