How to sum of two arrays in Python3:

Input Format:

The first line of the input contains a number N representing the number of elements in array A.
The second line of the input contains N numbers separated by a space. (after the last elements, there is no space)

Output Format:

Print the resultant array elements separated by a space. (no space after the last element)

Example:

Input:
4
2 5 3 1

Output:
3883

Explanation:
Here array A is [1,2,3,4] and reverse of this array is [4,3,2,1] and hence the resultant array is [5,5,5,5] 

SOURCE CODE:

import math
size=int(input())
list1=[]

for x in input().split():
  num=int(x)
  list1=list1+[num]
 
for i in range(math.ceil(size/2)):
    list1[i]=list1[size-1-i]=list1[i]+list1[size-1-i]
   
for i in range(size-1):
      print(list1[i],end=" ")
     
print(list1[size-1],end="")
