Question

In Python a class can inherit from more than one class (Java does not allow this). The resulting class will have all the methods and attributes from the parent classes. Do the following:

• Create a class called Person. In the class, define variables for storing date of birth, place of birth, and male/female attributes. In the class, define the constructor method, as well as methods for returning current values of the class attributes.

• Create a class called Employee. In the class, define variables for storing date of hire, department, and job title. In the class, define the constructor method, as well as methods for returning current values of the class attributes.

• Create a class called Salaried that inherits from both Person and Employee classes. In the class define variables for storing the salary and tax bracket. In the class, define the constructor method, as well as methods for returning current values of the class attributes.

• Instantiate a Salaried object using the following attribute default values: Date of birth: January 1, 1980; Place of birth: New York, NY; Male, Date of hire: May 1, 2005, Department: Finance; Job Title: Manager; Salary: 100000; Tax Bracket: 29%.

thanks for teh question, here is the complete set of classes in Python.

===================================================================

class Person():
    def __init__(self, dob, pob, gender):
        self.__birthDate = dob
        self.__birthPlace = pob
        self.__gender = gender

    def getBirthDate(self): return self.__birthDate

    def getBirthPlace(self): return self.__birthPlace

    def getGender(self): return self.__gender

    def setBirthDate(self, dob): self.__birthDate = dob

    def setBirthPlace(self, pob): self.__birthPlace = pob

    def setGender(self, gender): self.__gender = gender


class Employee():
    def __init__(self, doh, dep, title):
        self.__hireDate = doh
        self.__department = dep
        self.__jobTitle = title

    def getHireDate(self): return self.__hireDate

    def getDepartment(self): return self.__department

    def getJobTitle(self): return self.__jobTitle

    def setHireDate(self, doh): self.__hireDate = doh

    def setDepartment(self, dep): self.__department = dep

    def setJobTitle(self, title): self.__jobTitle = title


class Salaried(Person, Employee):
    def __init__(self, dob, pob, gender, doh, dep, title, sal, tax):
        Person.__init__(self,dob, pob, gender)
        Employee.__init__(self,doh, dep, title)
        self.__salary = sal
        self.__taxBracket = tax

   def getSalary(self): return self.__salary

    def getTaxBracket(self): return self.__taxBracket

    def setSalary(self, sal): self.__salary = sal

    def setTaxBracket(self, tax): self.__taxBracket = tax


def main():

    john = Salaried('January 1, 1980','New York, NY','Male','May 1, 2005','Finance','Manager',100000,29)
    print('Date of Birth :{}'.format(john.getBirthDate()))
    print('Birth Place:{}'.format(john.getBirthPlace()))
    print('Gender:{}'.format(john.getGender()))
    print('Hire Date:{}'.format(john.getHireDate()))
    print('Department:{}'.format(john.getDepartment()))
    print('Job Title :{}'.format(john.getJobTitle()))
    print('Salary :${}'.format(john.getSalary()))
    print('Tax Bracket :{}%'.format(john.getTaxBracket()))

main()
