What we see here is that as every dictionary doesn't have all the same keys pandas fills in the missing values with NaN. Next, we will look at how to access elements of the data frame.

We have done quite a lot here. The first thing is that we have defined the data frame based on the list of dictionaries as we showed previously. We then accessed all the elements of the column country by passing the name of the column as the key of the data frame. We next showed how we could access the first element of that by adding the index of the value we wanted. This is an important distinction as we aren't asking for the first element, we are instead asking for the value of the column with index value 0. Lastly, we select the rows of the country with index 0 and 1 in the usual way we would for a list, but again we are asking for specific index rows.
