Encapsulation
76.
How can encapsulation be enforced in Python to make a variable 'username' accessible only within its own class? 
class User:
    def __init__(self, username, __password):
        self.username = username
        self.__password = __password
Use a getter method for 'username'
Add a single underscore prefix before 'username'
Make 'username' a global variable
Add a double underscore prefix before 'username'
Answer: Option

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