What is the simplest way to aggregate two numeric arrays in pure Python?

Question

a = [1,2,3]
b = [4,5,6]

I want the output to be [5,7,9]

What is the simplest syntax that can achieve this in pure Python 3?

And the uglier version of @BuddyBob's answer : `c = list(map(sum, zip(a, b)))` — S.B, May 28 '21 at 18:29
Yes I like your answer @BuddyBob. I will accept it shortly if nothing nicer comes along :) — Mike, May 28 '21 at 19:32

I'd say using zip() would be a nice way

a = [1,2,3]
b = [4,5,6]
c = [x+y for x,y in zip(a,b)]

output

[5, 7, 9]
