Parts of a DataFrame

To better understand DataFrame objects, it's useful to know that they consist of three components:

values: A two-dimensional NumPy array, accessed via the .to_numpy() method.
columns: An index of column names, accessed via the .columns attribute.
index: An index for the rows, accessed via the .index attribute.

You can usually think of indexes as a list of strings or numbers, though the pandas Index data type allows for more sophisticated options. (These will be covered later in the course.)
