numpy sum array

when working with multi-dimensional arrays, users can specify the axis along which to perform the summation, enabling more granular control over the operation. this is particularly useful in data analysis, where summing over specific dimensions is often required.

using numpy to sum arrays not only improves code efficiency but also contributes to cleaner and more readable code. this makes it an essential tool for data scientists, engineers, and anyone involved in numerical computations.
