Using python map and other functional tools
...sequence1, sequence2)
is mostly equivalent to:
[f(x1, x2) for x1, x2 in zip(sequence1, sequence2)]
(there is a difference in how it handles the case where the sequences are of different length. As you saw, map() fills in None when one of the sequences runs out, whereas zip() stops when the sho...

...list2. In python:

xs = [1, 2, 3]
ys = [2, 4, 6]
def f(x, y):
return (x * 2, y...
