Exercise

Square Brackets (2)

Square brackets can do more than just selecting columns. You can also use them to get rows, or observations, from a DataFrame. The following call selects the first five rows from the cars DataFrame:

cars[0:5]

The result is another DataFrame containing only the rows you specified.

Pay attention: You can only select rows using square brackets if you specify a slice, like 0:4. Also, you're using the integer indexes of the rows here, not the row labels!
