[백준/python] 25206번 너의 평점은: dictionary 이용 key값 받아 value 얻기

 

gradeDict = {"A+": 4.5, "A0": 4.0, "B+": 3.5, "B0": 3.0,
        "C+": 2.5, "C0": 2.0, "D+": 1.5, "D0": 1.0, "F": 0.0}

sumofgrade=0.0
creditSum=0.0

for i in range(20):
    subject, credit, grade =input().split()
    
    if grade=='P':
        continue

    sumofgrade +=float(credit)*gradeDict[grade]
    creditSum+=float(credit)

GPA=sumofgrade/creditSum
print(GPA)

 

 

credit에 float형 붙여야함.
