Encapsulation

66.

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

class User:
    def __init__(self, username, password):
        self.username = username
        self.__password = password

Add a single underscore prefix before 'password'

Add a double underscore prefix before 'password'

Use a getter method for 'password'

Make 'password' a global variable

Answer: Option
