파이썬 블랙 잭
Aug 18 2020
Python으로 작성된 간단한 터미널 블랙 잭 게임. 기본 블랙 잭 규칙을 따릅니다. 블랙 잭은 3 대 1, Hit, Stick, Double Down 및 Splits Dealer hits는 17 일까지 지불합니다. 일부 데이터를 추적합니다. 내 객체 지향 프로그래밍 작업을 위해 작성했습니다. 좀 더 잘 할 수 있습니다, 감사합니다.https://github.com/jamucar/terminal-blackjack

답변

논리 1
def shuffle(self):
'''shuffle the card deck'''
if len(self.cards) > 1:
random.shuffle(self.cards)
len검사는 필요하지 않습니다. shuffle0 또는 1 요소가있는 목록에서 충돌하지 않습니다.
논리 2
if has_ace and self.value > 21:
self.value -= 10
Ace가 두 개 이상 있으면 어떻게 되나요? 그들 각각은 1첫 번째 로 계산할 수 있습니까? 여기에 논리적 오류가 있다고 생각합니다.
코드 1
def get_value(self):
'''calls calculate_value and returns the hand value'''
self.calculate_value()
return self.value
당신은 항상 그것을 반환하기 전에 값을 계산합니다. 이것은 좋은 것이라고 생각합니다.
그러나 그것은 또한 손에 값을 저장할 필요가 없다는 것을 의미 this.value합니다. 오히려 calculate_value()함수 에서 계산 된 값을 저장하지 않고 반환해야합니다 this.value.
그런 다음을 반환하기 때문에 calculate_value()및 함수가 모두 필요하지 않습니다 .get_value()get_value()calculate_value()
코드 개선 1
for i in range(len(self.cards)):
print("+---+ ", end="")
이 루프에서 색인이나 카드를 사용하지 않기 때문에 다음과 같이 긴 문자열을 직접 인쇄 할 수 있습니다.
print("+---+ " * len(self.cards), end="")
코드 개선 2
for i in range(len(self.cards)):
card = self.cards[i]
print("|{} | ".format(card.suit), end="")
이렇게 카드를 직접 반복 할 수 있습니다.
for card in self.cards:
print("|{} | ".format(card.suit), end="")
이름 지정 1
def get_bet(self):
'''returns bet amount'''
return self.amount
Getter 메서드는 일반적으로 가져 오는 변수와 같은 이름이 지정되므로 함수를로 def get_amount(self):변경하거나 amount이름을 지정할 변수를 변경해야 합니다 bet. 그러나 클래스 Bet이름이이므로 클래스 내부에 같은 이름의 변수를 갖는 것은 좋지 않으므로 메서드 이름을 변경하십시오.
미사용 코드
reader512 행과 width, height464 행 등과 같이 사용하지 않는 변수가 많이 있습니다. 예를 들어 PyCharm과 같은 코드 편집기를 사용하는 것이 좋습니다. 그러면 이러한 실수를 자동으로 찾아 내고보다 효율적으로 작업 할 수 있습니다.
