2D Numpy Arrays
2D Numpy Arrays Lets recreate the numpy arrays. If you ask for the type of these arrays,Python tells you that they are numpy.ndarray. `numpy`. tells you its a type that was defined in the numpy package. `ndarray` stands for n-dimensional array. The arrays `np_height` and `np_weight` are one-dimensional arrays, but its perfectly possible to create 2 dimensional, three dimensional, heck even seven dimensional arrays! You can create a 2D numpy array from a regular Python list of lists. Lets try to create one numpy array for all height and weight data of your family, like this: If you print out `np_2d` now, youll see that it is a rectangular data structure: Each sublist in the list, corresponds to a row in the two dimensional numpy array. From `np_2d.shape`, you can see that we indeed have 2 rows and 5 columns. `shape` is a so-called attribute of the `np2d` array, that can give you more information about what the data structure looks like.
