Simdi bu oyunda karti ilk ceken dealer yani bilgisayarsa ilk kagidi sakla seklinde kod yazilmis.
Parametre verilmediginde show_all_dealer_cards=False'dir.
Anlamadigim konu,
ilk kagitsa
> index == 0
el dealer yani dagitici pcde ise
> self.dealer
Blackjack gerceklesmemisse
> self.is_blackjack()
Peki ama anlamadigim satir bu :
not show_all_dealer_cards Bu kod show_all_dealer_cards=False anlamina mi gelir True anlamina mi gelir?
Peki neden soruyorum?
Basit bir fonksiyon dusunelim
def test(x):
### aslinda x=5 deme! ###
print(x+10)
test(5)Normalde parametreye bir deger gonderdimizde aslinda fonk icinde bu x = 5 demek.
PEKI def display(self, show_all_dealer_cards=False):
print(f"""{"Dealer's" if self.dealer else "Your"} hand:""")
# Dealer = False -> Player/Oyuncu eli.
# Dealer = True -> PC/Bilgisayar eli.

print("Value:", self.get_value())Bu kod blogunda show_all_dealer_cards=False ise, block icindede show_all_dealer_cards=False demek degilmidir? Peki boyleyse not show_all_dealer_cards TRUE dondurmesi gerekmez mi? True ise sacma olmuyor mu? yani ilk kart aciksa dagitici dealer ise ve tum kartlar aciksa anlamina gelir cunku. Kafa karisikligimi giderirseniz sevinirim.
Tesekkur ettim.
