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

List of 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:

Oceanian countries

The countries and capitals 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)

For each function you should make sure you have the right number of arguments, give your arguments sensible names and add data type suggestions.

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):

List of Oceania countries

What you should see for Oceania, for example.

 

When you've got this working, test if it works for a different continent name. 

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