평균 학점:<bound method Grade.avg_grade of <__main__.Grade object at 0x7f8a33862f70>>

무엇 때문에 이렇게 뜨는지 모르겠습니다...

밑에는 전체 코드입니다..

class Student:

def __init__(self, name, id, major):

self.Student_info = Student_info(name, id, major)

self.grade = Grade()

def print_report_card(self):

"""학생 성적표 출력 메소드"""

avg = self.grade.avg_grade

print("코드잇 대학 성적표\n\n학생 이름:{}\n학생 번호:{}\n소속학과:{}\n평균 학점:{}".\

format(self.Student_info.name, self.Student_info.id, self.Student_info.major, avg))

class Student_info:

def __init__(self, name, id, major):

self.name = name

self.id = id

self.major = major

def change_student_info(self, new_name, new_id, new_major):

self.name = new_name

self.id = new_id

self.major = new_major

class Grade():

def __init__(self):

self.grade = []

def add_grade(self, new_grade):

"""학점 추가하는 메소드"""

self.grade.append(new_grade) if 0 <= new_grade <= 4.3 else print("수업 학점은 0과 4.3사이여야 합니다!")

def avg_grade(self):

"""평균 학점 계산 메소드"""

total_grade = 0

for grade in self.grade:

total_grade += grade

return total_grade/len(self.grade)

# 작성한 클래스에 맞춰서 실행 코드도 바꿔보세요

younghoon = Student("강영훈", 20120034, "통계학과")

younghoon.Student_info.change_student_info("강영훈", 20130024, "컴퓨터공학과")

younghoon.grade.add_grade(3.0)

younghoon.grade.add_grade(3.33)

younghoon.grade.add_grade(3.67)

younghoon.grade.add_grade(4.3)

younghoon.print_report_card()
