Solution Exercise 42: Class Person and child class Student

 Exercice 42

1. Create a Python class Person with attributes: name and age of type string.
2. Create a display() method that displays the name and age of an object created via the Person class.
3. Create a child class Student  which inherits from the Person class and which also has a section attribute.
4. Create a method displayStudent() that displays the name, age and section of an object created via the Student class.
5. Create a student object via an instantiation on the Student class and then test the displayStudent method.

Solution:

class Person:
    # define constructor with name and age as parameters
    def __init__(self, name, age):
        self.name = name
        self.age = age
    # create display method fro Person class
    def display(self):
        print("Person name : ", self.name)
        print("Person age = ", self.age)
    
# create child class Student of Person class
class Student(Person):
    # define constructor of Student class with section additional parameters 
    def __init__(self, name , age , section):
        Person.__init__(self,name, age)
        self.section = section
    
    # Create display method for Student class
    def displayStudent(self):
        print("Student name : ", self.name)
        print("Student age = ", self.age)
        print("Student section = ", self.section)
    
# Testing Person class
P = Person("Tomas Wild", 37)
P.display()
print("-------------------------------")
S = Student("Albert", 23 , "Mathematics")
S.displayStudent()

The output is as follow:
Person name :  Tomas Wild
Person age =  37
-------------------------------
Student name :  Albert
Student age =  23
Student section =  Mathematics
