1. 조건문

 

 

def get_grade(score):
    # some code
    if score > 90:
        return "A"
    elif score > 80:
        return "B"
    elif score > 70:
        return "C"
    else:
        return "F"

score = int(input("점수를 입력 : "))
grade = get_grade(score)
print(grade) # A ~ F

 

 

2. 반복문(while) 

 

isdigit 함수를 통해 input된게 숫자인지 아닌지를 걸러내고

exit를 입력하거나(a == "exit") 다섯번 반복할때까지 (if cnt > 4: break) 반복.

뭔가 좀 더 깔끔하게 만들 수 있을거같은데 애매하네..

cnt = 0
while 1:
    a = input("문자 혹은 숫자를 입력 : ")
    if a == "exit":
        print("프로그램을 종료합니다.")
        exit()
    elif a.isdigit() == True:
        print(2*int(a))
        cnt += 1
        if cnt > 4:
            break
    elif a.isdigit() == False:
        print(f"입력한 문자는 {a}입니다.")
        cnt += 1
        if cnt > 4:
            break

 

 

 

 

3. 반복문(for) - 진행중

 

 

일단 패킹 언패킹 부분 안건드리고 단순하게 구상만 해보자면

이지만, 당연히 이렇게 만들면

이렇게 나오죠

filter 리스트를 만들고 안에 추가하는 형식으로 만들고싶은데

위의 코드는 추가가 아니라 filter가 계속 갱신되는 형태라서 맨 마지막만 출력되는걸 확인할 수 있다.

왜 안되는진 알겠는데 어떻게 되게 만드는질 모르겠네 아 ㅋㅋ

일단 제대로 돌아는 가게 만들었는데 암만봐도 영 깔끔하지가 않다 ㅋㅋ
