Question

How can I get the pairwise sum of two equal length tuples? For example if I have (0,-1,7) and (3,4,-7) I would like to have (3,3,0) as answer.

Answer 1

tuple(map(lambda (x, y): x + y, zip((0,-1,7), (3,4,-7))))

If you prefer to avoid map and lambda then you can do:

tuple(x + y for x,y in zip((0,-1,7), (3,4,-7)))

EDIT: As one of the answers pointed out, you can use sum instead of explicitly splitting the tuples returned by zip. Therefore you can rewrite the above code sample as shown below:

tuple(sum(t) for t in zip((0,-1,7), (3,4,-7)))

Reference: zip, map, sum.
