Exercise

loc and iloc (2)

loc and iloc also allow you to select both rows and columns from a DataFrame. To experiment, try out the following commands in the IPython Shell. Again, paired commands produce the same result.

cars.loc['IN', 'cars_per_cap']
cars.iloc[3, 0]

cars.loc[['IN', 'RU'], 'cars_per_cap']
cars.iloc[[3, 4], 0]

cars.loc[['IN', 'RU'], ['cars_per_cap', 'country']]
cars.iloc[[3, 4], [0, 1]]
