Task 3
Design the program to get the output as shown.
Subtasks:

[You are not allowed to change the code below]
# Write your code here for subtasks 1-4

b = Team()
b.setName(‘Bangladesh’)
mashrafi = Player(“Mashrafi”)
b.addPlayer(mashrafi)
tamim = Player(“Tamim”)

a = Team(“Australia”)
ponting = Player(“Ponting”)
a.addPlayer(ponting)
lee = Player(“Lee”)
a.addPlayer(lee)

Task 4
Look at the code and the sample inputs and outputs below to design the program
accordingly.
1. Write a class called Color that only adds the 3 primary colors (red, blue and
yellow).
2. Write a required constructor for the class.
3. You have to use operator overloading to get the desired outputs as shown.
Hint:
There will be only one constructor and only one method tackling the addition operation.
No other methods are required.
Note: Order of the color given as input should not matter. For example, in sample input
1, if the first input was yellow and then red, the output would still be orange.
#Write your code here
#Do not change the following lines of
code
C1 = Color(input(“First Color: “).lower())
C2 = Color(input(“Second Color: “).lower())
C3 = C1 + C2
print(“Color formed:”, C3.clr)
Sample Input 1:
First Color: red
Second Color: yellow
Sample Output 1:
Color formed: Orange
Sample Input 2:
First Color: red
Second Color: blue
Sample Output 2:
Color formed: Violet
Sample Input 3:
First Color: yellow
Second Color: BLUE
Sample Output 3:
Color formed: Green
Task 5
Write a class called Circle with the required constructor and methods to get the
following output.
Subtasks:
1. Create a class called Circle.
2. Create the required constructor. Use Encapsulation to protect the variables. [Hint:
Assign the variables in private]
3. Create getRadius() and setRadius() method to access variables.
4. Create a method called area to calculate the area of circles.
5. Handle the operator overloading by using a special method to calculate the radius
and area of circle 3.
[You are not allowed to change the code below]
# Write your code here for subtasks 1-5

c1 = Circle(4)
print(“First circle radius:” , c1.getRadius())
print(“First circle area:” ,c1.area())
c2 = Circle(5)
print(“Second circle radius:” ,c2.getRadius())
print(“Second circle area:” ,c2.area())
c3 = c1 + c2
print(“Third circle radius:” ,c3.getRadius())
print(“Third circle area:” ,c3.area())
Output:
First circle radius: 4
First circle area: 50.26548245743669
Second circle radius: 5
Second circle area: 78.53981633974483
Third circle radius: 9
Third circle area: 254.46900494077323
Task 6
Write a class called Triangle with the required constructor and methods to get the
following output.
Subtasks:
1. Create a class called Triangle.
2. Create the required constructor. Use Encapsulation to protect the variables. [Hint:
Assign the variables in private]
3. Create getBase(), getHeight(), setBase and setHeight() method to access
variables.
4. Create a method called area to calculate the area of triangles.
5. Handle the operator overloading by using a special method to calculate the radius
and area of triangle 3.

t3 = t1 – t2
print(“Third Triangle Base:” , t3.getBase())
print(“Third Triangle Height:” , t3.getHeight())
print(“Third Triangle area:” ,t3.area())
Output:
First Triangle Base: 10
First Triangle Height: 5
First Triangle area: 25.0
Second Triangle Base: 5
Second Triangle Height: 3
Second Triangle area: 7.5
Third Triangle Base: 5

compares the price of the objects.
Hints:
● Notice that the price of each object is being checked with the price of obj in the
given code.
● Notice the word Doll in the first 4 outputs and the last output. You have to print
