Public members (generally methods declared in a class) are accessible from outside the class. The object of the same class is required to invoke a public method. This arrangement of private instance variables and public methods ensures the principle of data encapsulation.

The behaviour of these variables is quiet different from other programming language. These access controls are just the naming conventions in python rather than actual hiding of objects.

To create a class, use the keyword class: Create a class named MyClass, with a property named x: Now we can use the class named MyClass to create objects: Create an object named p1, and print the value of x: The examples above are classes and objects in their simplest form, and are not really useful in real life applications.

When we define a Python class, any instance’s instance variables can be accessed within or outside of the class. For example, suppose we have a class named Person that represents a person and if they are a “child” (for our purposes, anyone under 18 years old is …
