Given the following classes, write the code for the BBA_Student class so that the following output is printed:
class Student:
def __init__(self, name=’Just a student’, dept=’nothing’):
self.__name = name self.__department = dept
def set_department(self, dept):
self.__department = dept
def get_name(self): return self.__name
def set_name(self,name):
self.__name = name
def __str__(self): return ‘Name: ‘+self.__name+’ Department: ‘+self.__department
#write your code here
print(BBA_Student()) print(BBA_Student(‘Humpty Dumpty’)) print(BBA_Student(‘Little Bo Peep’)) Output:
Name: default Department: BBA
Name: Humpty Dumpty Department: BBA

class Vehicle:
def __init__(self): self.x = 0 self.y = 0
def moveUp(self): self.y += 1
def moveDown(self): self.y -= 1
def moveRight(self): self.x += 1
def moveLeft(self): self.x -= 1
def __str__(self):
return ‘(‘+str(self.x)+’ , ‘+str(self.y)+’)’
#write your code here

A vehicle assumes that the whole world is a 2-dimensional graph paper. It maintains its x and y coordinates (both are integers). The vehicle gets manufactured (constructed) at (0, 0) coordinate.
Subtasks:
1. Design a Vehicle2010 class which inherits movement methods from Vehicle and adds new methods called move UpperRight, UpperLeft, LowerRight, LowerLeft. Each of these diagonal move methods must re-use two inherited and appropriate move methods.
2. Write an “equals” method which tests if significant class properties are the same (in this case x and y).
Note: All moves are 1 step. That means a single call to any move method changes value of either x or y or both by 1.
Task – 3
Given the following classes, write the code for the Cricket_Tournament and the Tennis_Tournment class so that the following output is printed.

ct1 = Cricket_Tournament() print(ct1.detail())
print(“———————–“) ct2 = Cricket_Tournament(“IPL”,10,”t20″)
print(ct2.detail())
print(“———————–“)

Player and the Manager class so that the
following output is printed. To calculate the match earning use the following formula:
1. Player: (total_goal * 1000) + (total_match * 10)
2. Manager: match_win * 1000
