함수 만들기

for문을 사용하여 A학급의 평균 점수를 구해보세요

class_A = [70,60,55,75,95,90,80,80,85,100]

def class_avg(class_A):

    for i in range(1,10) :
        total = total + class_A
        avg = total / 10

    return(class_avg)

class_avg()

이렇게 했더니

# TypeError: class_avg() missing 1 required positional argument: 'class_A' 라는 오류메시지가 나왔다...
