Read the data from the CSV file into a DataFrame and display the first five rows $(3$ pts$.).$ Check to see if any of the columns have missing values $(2$ pts$.).$ Display the unique values in the region column, and notice that one of the regions is TotalUS $(2$ pts$.).$ Drop rows that have a region of TotalUS, and then check to see how many rows were dropped $(3$ pts$.).$ Drop the Unnamed: $0,4046,4225,$ and $4770$ columns $(2$ pts$.).$ Convert the Date column to the DateTime type $(2$ pts$.).$ Check that these changes have been applied to the DataFrame $(2$ pts$.).$
