Answer 1

class Student(object):
    def getdata(self):
        self.roll_no = input("Enter roll number: ")
        self.name = input("Enter name: ")

    def printdata(self):
        print("Roll number:", self.roll_no)
        print("Name:", self.name)

class Marks(Student):
    def inputdata(self):
        self.getdata()
        self.marks = []
        for i in range(5):
            mark = float(input("Enter marks in subject " + str(i + 1) + ": "))
            self.marks.append(mark)

    def outdata(self):
        self.printdata()
        print("Marks in five subjects:", self.marks)

m = Marks()
m.inputdata()
m.outdata()
