how to add elements in the list in python with one loops or without loops or any direct functions

Question

I need code to sum lists. Example: [[1,2,3],[1,2,3]]. answer be like [2,4,6]. [[1,1,1],[2,2,2],[3,3,3]] answer: [6,6,6]

Answer 1

Refer this this can work for n number of list too and please try first, read docs, and provide relevant resources that you tried or code snippet.

[a+b+c for a,b,c in zip([1,1,1],[2,2,2],[3,3,3])]

Output: [6,6,6]

if you are okay with using packages use numpy and apply it but read it's documentation beforehand.

Answer 2

Perform a transpose operation, and then use sum():

lst = [[1,2,3],[1,2,3]]
[sum(sublist) for sublist in zip(*lst)]

This outputs:

[2, 4, 6]
