Learn to write cleaner, more modular, and more scaleable code in Python by gaining a master of Object Oriented Programming (OOP). 

You'll start with the basics of object oriented programming and build up to more advanced concepts such as inheritance, information hiding, and polymorphism. Along the way you'll learn how each concept applies to Python in particular, as well as how various Python features make it particularly convenient for OOP.

This course is filled with hands-on coding challenges, playgrounds, snippets, and illustrations to keep things interactive.

Learn Object-Oriented Programming in Python

In Python, we can impose access restrictions on different data members and member functions. The restrictions are specified through **access modifiers**. Access modifiers are tags we can associate with each member to define which parts of the program can access it directly.

There are two types of access modifiers in Python. Let's take a look at them one by one.



# Public attributes

> **Public attributes** are those that can be accessed inside the class and outside the class. 

Technically in Python, **all** methods and properties in a class are publicly available by default. If we want to suggest that a method should not be used publicly, we have to declare it as private explicitly.

Below is an example to implement public attributes:

class Employee:
    def __init__(self, ID, salary):
        # all properties are public
        self.ID = ID
        self.salary = salary

    def displayID(self):
        print("ID:", self.ID)


Steve = Employee(3789, 2500)
Steve.displayID()
print(Steve.salary)


hello

In the code above, the properties `ID` and `salary` and the method `displayID()` are *public* as they can be accessed in the class as well as outside the class.
