1. unittests are in a separate file from the Card class.

Card class is already defined and you are to use the one that is given.

2. The ideas (is comparisons for equality are correct, you just need to update your code to use the Card.py file that we have).

3. Keep in mind that we have access to class variables via class name

For example, Card.SUIT_NAMES
