Testing your code is a good idea because it usually leads to great improvements. There's many libraries in python that will help with testing but a favourable on called pytest. In this series of videos we demonstrate how the use it.
test_blackjack.py now has more tests.
from blackjack import card_score def test_simple_usecase1(): card_score("JK") == 20 def test_simple_usecase2(): card_score("JKQ") == 0 def test_simple_usecase3(): card_score("KA") == 21
