This word represents the characteristics or properties of an object.

attribute

200

A code template or "blueprint" used to create objects.

class

300

One specific instance of a class.

Object

400

What do we call the period in between an object and an attribute or method, such as:

self.name

Dot operator

_______ Bicycle():

     def __init__(self, myMake):

          self.make = myMake

class

200

class Person():

     def __init__(self, myName, myAge):

          self.name= myName

          self.age = myAge

dude = ________("Joey", 13)

Person

class Vehicle():

     def __init__(self, myColor, myModel):

          _______.color = myColor

          _______.model = myModel

self

400

class Pet():

     def __init__(self, mySpecies, myName):

          self.species = mySpecies

          self.name = myName

     def changeName(_______________):

          self.name = newName

self, newName

500

class Animal():

     def __init__(self, myName):

          self.name = myName

     def growl(self):

          print("Grrr.... says", myName)

______________ #creates an Animal named Fido

______________ #makes Fido growl

fido = Animal("Fido")

fido.growl()

class Soda():

     def __init__(self, myBrand, myFlavor, myPrice):

          self.brand = myBrand

          self.flavor= myFlavor

          self.price= myPrice

soda1 = Soda()

When making the object, it needs arguments.

ex.: soda1 = Soda("Coke", "Cherry", 2.99)

200

class Pet():

     def __init__(self, mySpecies, myName):

          self.species = mySpecies

          self.name = myName

     def printInfo(self):

          print("Species:", self.species)

          print("Name:", self.name)

fido = Pet("dog", "Fido")

print(fido)

You don't want to print an object directly. Instead, use the printInfo() method:

fido.printInfo()

300

class Player():

     def __init__(self, myX, myY):

          self.x= myX

          self.y= myY

          self.score= 0

player1 = Player(100, 200, 0)

A player is constructed with only the x and y as attributes; the points do not need to be specified as that is already done inside the body of the constructor. Should be:

player1 = Player(100, 200)

400

class Animal():

     def __init__(self, myName):

          self.name = myName

     def growl(self):

          print("Grrr.... says", myName)

myName is a parameter in the constructor, not growl(). It should use self.name instead.

500

class Animal():

     def __init__(self, myName):

          self.name = myName

class Cat():

     def __init__(self, myName, myBreed):

          super().__init__(myName)

          self.breed = myBreed

The parent class is never indicated. Should be:

class Cat(Animal):

Methods and Constructors

100

What is the first parameter of all methods?

self

200

What name do all constructors have?

__init__

300

A method is a __________ that is placed inside a _________.

function; class

400

Write a method, called ageUp that increases an attribute called age by 1.

def ageUp(self):

    self.age += 1

500

Write a constructor to be placed in a Coin class. The Coin should have three attributes (x, y, and points). A Coin can start at any (x, y) position, but should ALWAYS start with 5 points when created.

def __init__(self, myX, myY):

     self.x = myX

     self.y = myY

     self.points = 0

Inheritance

100

What is the function used to call a parent class?

super()

200

A _________ class is more general, while a ________ class is more specific.

parent; child

300

What happens if a method is defined in the parent class but not in the child class?

The child class inherits the method automatically without any changes.

400

What is it called when a child class executes its own version of a method rather than the one in the parent class. 

Overriding a method

500

What is the purpose of inheritance?

To allow child classes to reuse, extend, or customize functionality from a parent class without rewriting code.
