Exercise 1

Open the program called multilingual_greeter.py

• For each function, remove the line containing the pass statement and implement the functionality described in the docstrings.
• Run the unit tests to validate that the implementation passes unit tests.

python3 -m unittest test_multilingual_greeter.py

Once all tests are passing, you should be able to run the program.

Exercise 2

Create a program called multilingual_greeter_v2.py

Extend the functionality from exercise 1 so it meets the following requirements:

• When the application is executed, the user is prompted for admin mode or user mode.
• In admin mode, the user is given the choice perform the following actions:
  • Add support for additional languages.
  • Update greetings for existing languages.
• Be sure to create tests for all new functionality.
• Be sure to enhance existing tests where appropriate.

Exercise 3

Create a program called multilingual_greeter_v3.py

Extend the functionality from exercise 2 to meet the following requirements:

• Each key in the greetings dictionary is associated with a list rather than a string.
• Each list should contain at least 3 greetings per language.
• The greet function will select a random item from the list when invoked.
• Ensure appropriate support for these new features while in admin mode.
• As always, be sure to include appropriate test coverage.
