Q1.

def getDictionary(x):

    file=open(x,'r')

    Dict={}

    for line in file:

        a=line.split()

        Dict[a[0]]=int(a[1])

    return(Dict)

    file.close()

Q2.

def getMaxScore(x):

    x=getDictionary(x)

    y=max(x)

    s=x['y']

    s=int(s)

    return (y,s)

# 아래는 테스트용 코드이며 삭제해도 무방함

x = getDictionary("score.txt")

print(x)

(student,score) = getMaxScore(x)

print(student,score)
