Make a class names Foo Add a class variable to foo called x and initialize it to 5 Add an instance variable to foo called y and initialize it to 100 Make an instance of the class, call it f Using Foo., print out the value of x (proper etiquette for class variables) Using f., Print out the value of y (proper etiquette for instance/self. variables) Hint: remember that class variables are the ones where their value is the same for all instances/clones. And instance variable (which you declare inside the __init__ method with the self. preface, are unique to each clone. When you print a class variable the proper way is to use classname . (for example Foo.x) and when you print an instance variable you use the instance handle (for example f.y.)
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:
python3:
Class vs Instance variable
- Make a class names Foo
- Add a class variable to foo called x and initialize it to 5
- Add an instance variable to foo called y and initialize it to 100
- Make an instance of the class, call it f
- Using Foo., print out the value of x (proper etiquette for class variables)
- Using f., Print out the value of y (proper etiquette for instance/self. variables)
Hint: remember that class variables are the ones where their value is the same for all instances/clones. And instance variable (which you declare inside the __init__ method with the self. preface, are unique to each clone. When you print a class variable the proper way is to use classname . (for example Foo.x) and when you print an instance variable you use the instance handle (for example f.y.)
