Challenge: User Auth
Opgave
Swipe to start coding
Let's improve your User class!
- Create the class attribute
is_authenticatedin theUserclass. - Define the
login()method that takes argumentsselfandtaken_password. - The
login()method should compare the user and taken passwords.
If the user password is equal to the taken password, theTrueshould be assigned to theis_authenticatedattribute.
If the user password is not equal to the taken password, the"Wrong password!"should be written in the console. - Define the
logout()methods. This method should assign theFalsevalue to theis_authenticatedinstance attribute.

class User:
is_authenticated = False
def __init__(self, username, password):
self.username = username
self.password = password
def login(self, taken_password):
if self.password == taken_password:
