01-Object Orientated Programming

 1. Python is NOT an object orientated language.

  True

  False

 2. Object Orientated programming ...
#Example of Object Orientated code - use of classes
class Person:
    def __init__(self, name):
        self.name = name

    def say_hi(self):
        print('Hello, my name is', self.name)

p = Person('Mr Joey Bloggs')
p.say_hi()

  allows for the creation of objects that can be directly manipulated by the cache

  allows for the use of inheritance and capsule hunting which utilises classes

  allows for the use of polymorphism where objects hide data and methods at all times

  allows for the use of classes and objects combine methods and data(attributes)

 3. The OOP approach differs from the procedural approach in that ...

  Procedural programming languages separate data and code.

  Procedural programming languages are much slower to use

  Procedural programming languages use classes and morphs

  Procedural programming languages do not separate data and code

 4. In OOP, the programmer can use classes. A class ...

  acts as a template for an object. It contains shared attributes and methods.

  acts as a function that keeps all the functions inside it hidden from anyone

  acts as a blueprint which is completely empty, containing no attributes and methods

  acts as a 'school' in which there are many classes

 5. The concept of OOP revolves around the idea of the world we live in with objects. The OOP definition of an object is:

  an object is an instance of a function

  an object is a mini class that exists within a class

  an object is an individual instance of a class.

  an object is a class orientated world template

 6. Object-oriented programming allows for simplified programming. Its benefits include ...

  instantiation, creation of objects from functions, quick processing

  reusability, refactoring, extensibility, maintenance and efficiency.

  hard coded solutions, attributes and methods kept contained, object instances

  the ability to keep code separate from itself, i.e non reusability

 7. There are four pillars of OOP (features of OOP that are widely used). One of them is 'Abstraction'. Which of the following is NOT a feature of OOP?

  inheritance

  validation

  encapsulation

  polymorphism

 8. Generally speaking, OOP has been the programming model of choice for the last decade or more. OOP's modular design enables programmers to build software in manageable chunks rather than in large amounts of sequential code

  False

  True

 9. Which of the following is NOT a benefit of OOP:

  non-reusability - classes are hidden so they cannot be reused

  re-usability of code and ease of testing

  scalability -with objects and definitions having no finite limitation

  separation of data from method

 10. OOP promotes a way of programming that allows programmers to think in terms of Objects

  True

  False
