Answer 1

import datetime

class Person:

def __init__ (self,firstname,lastname,dob):

self.fname = firstname

self.lname = lastname

self.dob = dob

def getFullname(self):

return str(self.fname) + " " + str(self.lname)

return str(dob)

def getAge(self):

tokens = self.dob.split("/")

iMonth = tokens[0]

iDay = tokens[1]

iYear = tokens[2]

print("year:month:day=" + str(iYear) + ":" + str(iMonth) + ":" + str(iDay))

today = datetime.date.today()

birthdate = datetime.date(int(iYear),int(iMonth),int(iDay))

years = int(today.year) - int(birthdate.year)

if today.month < birthdate.month or (today.month == birthdate.month and today.day < birthdate.day):

years -= 1

return years

class Student(Person):

def __init__(self,firstname,lastname,dob,studentid,gradelevel):

Person.__init__(self,firstname,lastname,dob)

self.studentID = studentid

self.courseMarks.update({x:y})

def getTotal(self):

#print (marks)

#print(len(marks))

sum=0

for mark in marks:

if mark!="mark":

sum = float(sum) + float(mark)

return sum

def getAverage(self):

return self.getTotal()/(len(self.courseMarks)-1)
