# Write a function that accepts two parameters: a city name and a
# country name. The function should return a single string of the form
# City, Country, such as Santiago, Chile. Store the function in a module
# called city_functions.py.

# Create a file called test_cities.py that tests the function you just
# wrote (remember that you need to import unittest and the function you
# want to test). Write a method called test_city_country() to verify
# that calling your function with values such as 'santiago' and 'chile'
# results in the correct string. Run test_cities.py, and make sure
# test_city_country() passes.
