Python Program to find the sum of array

In this article, we will learn about the solution and approach to solve the given problem statement.

Problem statement

Given an array as an input, we need to compute the sum of the given array.

Here we may follow the brute-force approach i.e. traversing over a list and adding each element to an empty sum variable. Finally, we display the value of the sum.

We can also perform an alternate approach using built-in sum function as discussed below.

Example

# main
arr = [1,2,3,4,5]
ans = sum(arr,n)
print ('Sum of the array is ',ans)

Output

15

All the variables & functions are declared in the global scope and are shown below.

Conclusion

In this article, we learnt about the approach to find the sum of an array.
