Write 3 functions to complete a system to extract countries from any given CSV file

This exercise is provided to allow potential course delegates to choose the correct Wise Owl Microsoft training course, and may not be reproduced in whole or in part in any format without the prior written consent of Wise Owl.

Before you can do this exercise, you'll need to download and unzip this file.

The folder above contains 6 CSV files and one Python program file. Here are the CSV files:

Each of these is a text file containing a list of countries in that continent, together with the country's capital city.

Here's what the Oceania file looks like, for example:

The countries and capital cities of Oceania.

The Python program contains this code, but it needs a bit of work!

def get_contents_of_file(Argument_or_arguments_to_go_here):

# this needs writing!

pass

def get_country_dict(Argument_or_arguments_to_go_here):

# this needs writing!

pass

def print_results(Argument_or_arguments_to_go_here):

# this needs writing!

pass

# choose continent to show data for

continent_name = "Oceania"

# get text from file for given continent name

country_list = get_contents_of_file(continent_name)

# from this extract a list of countries and cities

countries = get_country_dict(country_list)

# list them out

print_results(continent_name,countries)

Your task is to write the functions so that when you run the program you get this (if you set the continent name to Oceania, for example):

Try running your program for a couple of different continents to check it works.

A final thought: what happens if you try the continent name as Antarctica? Can you make your program do something sensible in this case?

You can unzip this file to see the answers to this exercise, although please remember this is for your personal use only.
