Python 중급 문제풀이 2

모듈

• 과목별 점수를 입력하면 합격 여부를 출력하는 모듈을 만들어보자.
• 평균 60이상 합격, 과락 40으로 한다.

코드

def exampleResult(s1, s2, s3, s4, s5):

    passAvgScore = 60
    limitScore = 40

    def getTotal():
        totalScore = s1 + s2 + s3 + s4 + s5
        print(f'총점: {totalScore}')
        return totalScore

    def getAverage():
        avg = getTotal() / 5
        print(f'평균: {avg}')
        return avg

    def printPassOrFail():
        print(f'{s1}: Pass') if s1 >= limitScore else print(f'{s1}: Fail')
        print(f'{s2}: Pass') if s2 >= limitScore else print(f'{s2}: Fail')
        print(f'{s3}: Pass') if s3 >= limitScore else print(f'{s3}: Fail')
        print(f'{s4}: Pass') if s4 >= limitScore else print(f'{s4}: Fail')
        print(f'{s5}: Pass') if s5 >= limitScore else print(f'{s5}: Fail')

    def printFinalPassOrFail():

        if getAverage() >= passAvgScore:
            if s1 >= limitScore and s2 >= limitScore and s3 >= limitScore and s4 >= limitScore and s5 >= limitScore:
                print('Final Pass!!')

            else:
                print('Final Fail!!')

        else:
            print('Final Fail!!')

    getAverage()
    printPassOrFail()
    printFinalPassOrFail()
