11th Chapter

11-1 Cities and countries: write a function that accepts two parameters: a city name and a country name. This function returns a format of the city, country string, such as Santiago, Chile. Will
This function is stored in a module named city_functions.py.
Create a program named test_cities.py and test the function you just wrote (Don't forget, you need to import the module unittest and the function you want to test). Write a test_city_country () that is named
method to verify that the resulting string is correct using a value similar to ' Santiago ' and ' Chile ' to invoke the aforementioned function. Run Test_cities. PY, confirm the test
Test Test_city_country () passed.
11-2 Population: Modify the previous function to include the third necessary formal parameter population, and return a string formatted as city, country-population xxx,
such as Santiago, Chile-population 5000000. Run test_cities.py to confirm that the test test_city_country () failed.
Modify the above function to set the parameter population to optional. Run test_cities.py again and confirm that the test test_city_country () has passed again.
Write a test called test_city_country_population () and verify that you can use values like ' Santiago ', ' Chile ' and ' population=5000000 ' to invoke
This function. Run test_cities.py again to confirm that the test test_city_country_population () passed.

11-3 Employee: Write a class called employee, whose method __init__ () accepts first, last, and yearly, and stores them in the attribute. Write a method named Give_raise (), which defaults to
The annual salary increase of $5000, but also can accept other salary increase.
Write a test case for employee that contains two test methods: Test_give_default_raise () and Test_give_custom_raise (). Use the method Setup () to avoid
A new employee instance is created in each test method. Run the test case and confirm that two tests have passed.
