Formatted string "City, Country" b. For example, "Santiago, Chile" b. Create a file called "YOUR_NAME_CityCountry_test.py" i. Use the unittest module to write multiple test cases to test the "format_city_country_string" function. ii. Test Scenarios to consider: 1. City and Country parameters are provided 2. City is an empty string 3. Country is an empty string 4. City is not a string data type 5. Country is not a string data type iii. These test scenarios should guide your programming logic. Essentially, what should your function do based on each test scenario? 1. Update the function as needed to get these test scenarios to pass. c. Submit both files for this assignment
