OOPLecture 06

OOP?Stands for object oriented programming.You’ve been using it all along.Anything you use the dot ‘.’ on is an object.

Methods and Variables Objects have methods and variables

# Getting a variableself.rect.x # Using a methodmylist.append(54)

ClassesAll objects belong to a classObjects are instances of a classClasses are like a blueprint for objects

Making Classes

class Ball():   def __init__(self, name):      self.bounce = False      self.name = name

AbstractionGetting all the necessary information for you needs.

Adding Methods

class Ball():   def __init__(self, name):      self.bounce = 5      self.name = name   def bounce_ball(self):      self.bounce = True

Using the ClassesThis means instantiating them, and creating different versions of them

ball1 = Ball("Tennis")ball2 = Ball("Basket")ball3 = Ball("Base") ball1.bounce_ball()print ball1.nameprint ball1.bounceprint ball2.bounce

Calling MethodsMethods are functions on objects.We call them using the ‘.’ operator
