I am learning Python for a few weeks. Last time I started object-oriented programming and I feel like it is really hard for me to write relation between methods and attributes different objects.
I tried to write simpler version BlackJack card game only with Hit or Stand option.
Could you have a look at my code and possibly give me some advices what should i change or improve?
