 It is important to note that NumPy doesn't really create this broadcasted version of `y` behind the scenes; it is able to do the necessary computations without having to redundantly copy its contents into a shape-(3,4) array. Doing so would be a waste of memory and computation. That being said, this replication process conveys exactly the mathematics of broadcast operations between arrays; thus the preceding diagram reflects how you should always envision broadcasting.

 Broadcasting is not reserved for operations between 1-D and 2-D arrays, and furthermore both arrays in an operation may undergo broadcasting. That being said, not all pairs of arrays are broadcast-compatible.

 See that the `/` operator, when used in conjunction with a `Path` instance, created a new path with the appropriate path-separator for the present OS. This is extremely convenient! 
 
 Let's proceed to explore some other useful methods that `Path` provides us with. These methods enable us to inspect directories and files, create new directories, list all of the files in a directory, open files to for reading/writing, and much more. A complete listing of these methods can be found [here](https://docs.python.org/3/library/pathlib.html#methods-and-properties) and [here](https://docs.python.org/3/library/pathlib.html#methods), collectively; it is highly recommended that you take time to look through them.
