(일단 코드작성 후, 실패했지만) 소감

10일차 수업과 11일차 수업사이에 간격이 꽤 있었다.

10일차 수업까지 배운걸 모두 녹여내는 캡스톤 프로젝트라니.. 11일차 수업을 앞두고 되게 많이 무서웠고, 여기서 며칠을 써야될까봐 겁이 났는데 꼬박 거의 하루반만에 해냈다

비록 모범답안과는 거리가 먼 코드일지라도 혼자 코드를 최대한 써봤다는게 뿌듯하다

못할 줄 알았다. 배운게 기억이 안날 것 같았다. 막막했다. 플로우차트 짜려고 생각하니 엄두가 안났다.

근데 코드가 짜졌고 비스무리하게나마 실행이 됐다. 이렇게 차근차근 가보자

#Hint 6: Create a function called calculate_score() that takes a List of cards as input 
#and returns the score. 
#Look up the sum() function to help you do this.
def calculate_score(cards):
  #Hint 7: Inside calculate_score() check for a blackjack (a hand with only 2 cards: ace + 10) and return 0 instead of the actual score. 0 will represent a blackjack in our game.

If the computer has a blackjack (0), then the user loses. If the user has a blackjack (0), then the user wins. If the user_score is over 21, then the user loses. If the computer_score is over 21, then the computer loses. If none of the above, then the player with the highest score wins.

(복습 후) 느낀 점

전부다 def로 처리하고 실행문은 아래와 같이 간단하게 만들다니 놀랍다..!

while input("Do you want to play of Blackjack? Type 'y' or 'n': ") == 'y':
  clear()
  play_game()

 

나는 flowchart를 그려놓고 flowchart 절차대로 코드를 짰다면

모범답안은 flowchart안에서도 def와 while을 활용하여 다시 구조를 갖추었다.

 

여전히 def와 while을 잘사용하지 못하는 나에게 많은 깨달음을 주는 코드작성문이다.

(특히 while not is_game_over: 와 같이 True/False를 임의로 지정해주는 변수를 잘 만들어내지 못한다)

 

화면에 띄울 텍스트와 텍스트(질문 또는 결과)사이에 어떤 계산들을 해주어야하는지를 구조를 갖춘 것으로 보인다.
