# Square Brackets (1)

In the video, you saw that you can index and select Pandas DataFrames in many different ways. The simplest, but not the most powerful way, is to use square brackets.

In the sample code on the right, the same cars data is imported from a CSV files as a Pandas DataFrame. To select only the `cars_per_cap`

column from `cars`

, you can use:

```
cars['cars_per_cap']
cars[['cars_per_cap']]
```

The single bracket version gives a Pandas Series, the double bracket version gives a Pandas DataFrame.

Instructions

**100 XP**

- Use single square brackets to print out the
`country`

column of`cars`

as a Pandas Series. - Use double square brackets to print out the
`country`

column of`cars`

as a Pandas DataFrame. - Use double square brackets to print out a DataFrame with both the
`country`

and`drives_right`

columns of`cars`

, in this order.
