One of the many dependencies of `matplotlib`

is called ** numpy**, which is short for “numerical Python.” It’s a very popular library used for scientific computing.

`numpy`

provides objects that can represent more complex data than the built-in data types in Python can. It also provides efficient yet advanced mathematical operations you can perform on this data.

In this course, you’ll use `numpy`

mostly to generate pseudorandom numbers, which you’ll then store in multidimensional arrays.
