This is an implementation of the MailList problem.
The idea is to work with a code, that is not yours. Navigate around the code and see how things are done.
After this, it's time for some refactoring in teams:
- Fix bugs, if any (hint - run the tests with
python run_tests.py) - Replace the files with sqlite for storage
- Implement the rest of the functionality
Everything should be done in OOP way with Test Driven Development approach in teams of 2.
