The file world-cities-populations.csv is a comma-separated file that lists cities, populations and country for a large number of cities around the world. Write a program that takes as input this file. Load the entries into a dictionary where the key is the city name as it appears in the file, and the value is a tuple containing the population and country. Submit your source code as well as a session record of your program running and returning populations for any three cities.

Modify the program above to add a check to verify that the population field is a number. You do this by trying to convert the number to an integer, and surrounding that code with a try-except block. Submit your code.

Write a program that loads the world-cities-populations.csv file into a pandas data frame. Print a list of the cities in North America to the console.
