There are two ways to find the sum of all array elements, 1) traverse/access each element and add the elements in a variable sum, and finally, print the sum. And, 2) find the sum of array elements using sum() function.

# Python program for sum of the array elements
# functions to find sum of elements
# Approach 1
def sum_1(arr):
result = 0
for x in arr:
result += x
return result
# Approach 2
def sum_2(arr):
result = sum(arr)
return result
# main function
if __name__ == "__main__":
arr = [10, 20, 30, 40, 50]
print ('sum_1: {}'.format(sum_1(arr)))
print ('sum_2: {}'.format(sum_2(arr)))
