Cześć 

 

Otot kod: 

class Card(object):
    RANKS = ["A","2","3","4","5","6","7","8","9","10","J","K"]
    SUITS = ["c","d","h","s"]

    def __init__(self,rank,suit):
        if rank not in RANKS:
            print("Nie ma takiej karty")
        else:
            self.rank = rank
        if suit not in SUITS:
            print("Nie ma takiej figury")
        else:
            self.suit = suit

    def __str__(self):
        rep = self.rank + self.suit
        return rep







nowakarta = Card("A","c")
print(nowakarta)
zlakarta = Card("Z","f")
print(zlakarta)

Jestem na etapie nauki OOP w Pythonie i chciałbym wiedzieć dlaczego w konsoli wyskakuje mi błąd podany w tytule.
