OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
an object can have_____ value if it refers to no object at all
java
Step by step
Solved in 2 steps
- A(n) _______ is a special constructor, called whenever a new object is initialized with another object’s data.Class AssignmentResult An object that represents the result of an assignment. __init__(self, id:int, assignment: Assignment, grade: float): """ This will contain the ID of the student, the assignment that the student worked on and the grade the student received on the assignment. :param id: The ID of the student that created this Assignment result :param assignment: The Assignment that the student worked on. :param grade: A number between 0-1 representing the numerical grade the student received """ get_id(self) -> int: """ Returns the ID of the student as specified in the constructor. :return: The student's ID """ get_grade(self) -> float: """ Returns the grade as specified in the constructor. :return: The grade the student received for this assignment """ get_assignment(self) -> Assignment: """ Returns the assignment as specified in the constructor. :return: The assignment that the student worked on to…A object which overloads the () operator is called a _______. Group of answer choices overload operator function object Overload object constructor object
- Fill-in-the-Blank A constructor is automatically called when an object is _________.True or false: The default constructor is the only constructor that may be called for objects in an array of objects.class TicTacToePlayer: # Player for a game of Tic Tac Toe def __init__(self, symbol, name): self.symbol = symbol self.name = name def move(self, board): move = int(input(self.name + " make your move 1-9:")) move -= 1 y = move % 3 x = move // 3 board[x][y] = self.symbol def is_symbol(self, symbol): if symbol == self.symbol: return True class TicTacToe: # Game of TicTacToe in a class! def __init__( self, p1_symbol="X", p2_symbol="O", p1_name="Player1", p2_name="Player2" ): self.p1 = TicTacToePlayer(p1_symbol, p1_name) self.p2 = TicTacToePlayer(p2_symbol, p2_name) self.board = [[" " for x in range(3)] for x in range(3)] def play_game(self): turn = 0 winner_symbol = False while not winner_symbol: self._print_board() if turn % 2: self.p2.move(self.board) # replace this line with a call…
- An object is a(n) ______ of a class.Operator typeid returns a reference to a(n)__________ object.Class Assignment This object represents a school assignment that a student will work on. __init__(self, name: str, difficulty: float): """ Constructs an assignment with the given assignment name and a float that indicates the level of difficulty of the assignment. :param name: The name of the assignment :param difficulty: The level of difficulty of the assignment """ get_name(self) -> str: """ Returns the name of the assignment as specified in the constructor. :return: The assignment name """ get_difficulty(self) -> str: """ Returns the level of difficulty of the assignment as specified in the constructor. :return: The assignment level """ __str__(self) -> str: """ Returns the name of the assignment as specified in the constructor. :return: The assignment name """
- Focus on classes, objects, methods and good programming style Your task is to create a BankAccount class. Class name BankAccount Attributes _balance float _pin integer Methods init () get_pin() check pin () deposit () withdraw () get_balance () The bank account will be protected by a 4-digit pin number (i.e. between 1000 and 9999). The pin should be generated randomly when the account object is created. The initial balance should be 0. get_pin () should return the pin. check_pin (pin) should check the argument against the saved pin and return True if it matches, False if it does not. deposit (amount) should receive the amount as the argument, add the amount to the account and return the new balance. withraw (amount) should check if the amount can be withdrawn (not more than is in the account), If so, remove the argument amount from the account and return the new balance if the transaction was successful. Return False if it was not. get_balance () should return the current balance.…Fill-in-the-Blank A(n)__________ is a special constructor, called whenever a new object is initialized with another object’s data.class Student: def __init__(self, id, fn, ln, dob, m='undefined'): self.id = id self.firstName = fn self.lastName = ln self.dateOfBirth = dob self.Major = m def set_id(self, newid): #This is known as setter self.id = newid def get_id(self): #This is known as a getter return self.id def set_fn(self, newfirstName): self.fn = newfirstName def get_fn(self): return self.fn def set_ln(self, newlastName): self.ln = newlastName def get_ln(self): return self.ln def set_dob(self, newdob): self.dob = newdob def get_dob(self): return self.dob def set_m(self, newMajor): self.m = newMajor def get_m(self): return self.m def print_student_info(self): print(f'{self.id} {self.firstName} {self.lastName} {self.dateOfBirth} {self.Major}')all_students = []id=100user_input = int(input("How many students: "))for x in range(user_input): firstName = input('Enter…
