Övningsinstruktioner

We have already imported pandas as pd, tickers and listings as in the previous exercises.

Inspect listings and print tickers.
Use .loc[] with the list of tickers to select the index components and the columns 'Market Capitalization' and 'Last Sale'; assign this to components.
Print the first five rows of components.
Create no_shares by dividing Market Capitalization by 'Last Sale'.
Print no_shares in descending order.
