Operating on lists and arrays
Operators, like +, work differently when applied to NumPy arrays and lists. When two NumPy arrays are added together with +, Python adds the two arrays together element-by-element and returns a new array of the same shape as the original arrays. This is similar to how MATLAB handles addition with matrices.
On the other hand, adding two lists together with + in Python concatenates them. While lists and arrays may appear to be interchangeable, if you aren't careful, these differences can lead to some unpleasant surprises.
In this exercise, you'll explore how the + operator works for NumPy arrays and lists.
