Question

[python3]

Start by using UML and planning the functionality of each method (including the constructor, that is, the __init__() method)

Initialization of your objects must require at least one parameter (in addition to self)

All of your objects attributes/fields should be 'private' and you should include getters and setters for each attribute/field

You must be able to print your object in a meaningful way and you should define what it means for two objects to be equal

Additionally, your object must do one trick (e.g., generate a random number or change color)

Implement a Class in Python for your newly designed object

Create three objects: two that are equal and one that is not and show that this is true

.

Make it as easy as possible please.

Answer 1

class Complex:

    # constructor

    def __init__(self, real = 0, imag = 0):

   

        self.real = real

        self.imag = imag

       

    # setter method

    def setReal(self, real):

   

        self.real = real

       

    def setImaginary(self, imag):

   

        self.imag = imag

       

    # getter method

    def getReal(self):

   

        return self.real

       

    def getImaginary(self):

   

        return self.imag

       

    # overload == operator

    def __eq__(self, ob):

   

      return self.real == ob.getReal() and self.imag == ob.getImaginary()

       

    def __str__(self):

   

        return '( ' + str( self.real ) + ' , ' + str( self.imag ) + ' )'

       

ob1 = Complex( 2 , 3 )

ob2 = Complex( 2 , 3 )

ob3 = Complex( 4 , 8 )

print('ob1 : ' + str(ob1))

print('ob2 : ' + str(ob2))

print('ob3 : ' + str(ob3))

print('Is ob1 equal to ob2 : ' , ob1 == ob2 )

print('Is ob1 equal to ob3 : ' , ob1 == ob3 )
