Python: Compute the sum of elements of a given array of integers

Python map: Exercise-11 with Solution

Write a Python program to compute the sum of elements of a given array of integers, use map() function.

Sample Solution:

Python Code :

from array import array
def array_sum(nums_arr):
    sum_n = 0
    for n in nums_arr:
        sum_n += n
    return sum_n

nums = array('i', [1, 2, 3, 4, 5, -15])
print("Original array:",nums)
nums_arr = list(map(int, nums))
result = array_sum(nums_arr)
print("Sum of all elements of the said array:")
print(result)

Sample Output:

Original array: array('i', [1, 2, 3, 4, 5, -15])
Sum of all elements of the said array:
0
