Read in the data file and save its contents as a DataFrame object. Please label the columns appropriately.

Print out how many countries in the dataset are in North America.

Print out how many countries are in each of the landmasses. Do this once using explicit loops to go through the data items $($i$.$e$.,$ without using the testing and aggregation capabilities of DataFrames$)$ and once without using explicit loops.

Print out the total population $($in millions$)$ of the countries that speaks each language. Then, print out the total population $($in millions$)$ of the countries that speak each language whose national populations are less than $50$ million. In both cases, print the populations in decreasing order of total population. Any conclusions you can make from the different charts?
