Encapsulation

88.

How can encapsulation be enforced in Python to make a variable 'serial_number' accessible only within its own class?

class ElectronicDevice:
    def __init__(self, serial_number, __brand):
        self.serial_number = serial_number
        self.__brand = __brand

Use a getter method for 'serial_number'

Add a single underscore prefix before 'serial_number'

Make 'serial_number' a global variable

Add a double underscore prefix before 'serial_number'

Answer: Option

Explanation:

Adding a double underscore prefix before 'serial_number' makes it a private variable, enforcing encapsulation within the class.
