This data is taken from http://www.clickz.com/ and represents statistics about the world population of Internet users, and the number of Internet Service Providers dating from a few years back.
  • Study the program and make sure you understand how the data is coded, and how the code works. There are no new Python constructs in this code. We have seen all the Python constructs used in this program in class or in a lab before!

Your assignment

Your assignment is to add new functions to this program so that we get a finer quantitative view of the world in terms of its usage of the Internet.

Question 1
Add a new function that will received the statistics list as parameter and that will print the 10 top countries in the world by order of their population. This function should be called from the main() function and should use the same format as the one shown above, i.e. with the country name listed first, then the population, then the Active users, then the users, then the ISPs.
