Sum of corresponding elements of list in Python

This sharing will describe how to sum the corresponding elements of multiple lists in Python, provided that the length of each list is the same. For example: a=[1,2,3], b=[2,3,4], c=[3,4,5], sum the corresponding elements of a, b, c, the output should be [6, 9,12].
　　
Method 1:
　　Direct solution, according to the principle of adding corresponding elements, you can first define a function.

def list_add(a,b):
    c = []
    for i in range(len(a)):
        c.append(a[i]+b[i])
    return c

if __name__ == '__main__':
    a = [1,2,3]
    b = [2,3,4]
    c = [3,4,5]
    print(list_add(list_add(a,b),c))

Method 2:
　　Use the numpy module to solve the problem.

import numpy as np
a = np.array([1,2,3])
b = np.array([2,3,4])
c = np.array([3,4,5])
print(a+b+c)

It should be noted that the type after a+b+c is numpy.ndarray.
Method 3:
　　Use the sum() function of the numpy module to solve.

import numpy as np
a = [1,2,3]
b = [2,3,4]
c = [3,4,5]
print(np.sum([a,b,c], axis = 0))

The axis parameter represents vertical summation.
