Chapter 10, Problem 1SA

Explanation of Solution

Encapsulation:

• • It combines the data and code into a single object.
• • It helps in restricting access to the methods.
• • This helps in preventing the data from being modified due to accident.
• • The object’s variable is not directly accessible.
• • Underscore helps in preventing the data from being accessed directly.

The encapsulation rules in python can be summarized as follows:

Public method	It is accessible from anywhere.
Public variables	It can be accessed from anywhere.
Private method	It can be accessed only in their own class.
Private method	It is accessible only in their class or method.

• • It protects the data from being tampered. By declaring the data field as private, direct modifications of properties are prevented.
• • It makes the class easy to maintain and reduces the errors...
