python parallel list comprehension
# Use zip() to generate an single iterable from 2 lists: zip([1, 2, 3], ["a", "b", "c"]) >> [(1, "a"), (2, "b"), (3, "c")] example: xs = [some list] ys = [some other list] func(x,y): return some value [func(x, y) for x, y in zip(xs, ys)] will iterate over both lists simultaneously, running func() over each pair of values
