Challenge: AbstractAdmin

Tâche

Swipe to start coding

Let's protect your Admin class structure! You need to define the AbstractAdmin class that should have the strict Admin class structure.

Import the ABC class and abstractmethod decorator from the abc package.
Define the AbstractAdmin class inherited from the ABC class.
Define the abstract methods login(), logout(), create_content(), update_content(), and delete_content() via the @abstractmethod decorator.
Use the pass keyword to miss the function implementation.
Inherit the Admin class from the AbstractAdmin class.
Try to run the code with comments. Look at the Traceback.
Delete comments in the Admin class and run the code again.

Note

Abstract methods should not receive arguments.

Solution

from abc import ABC, abstractmethod

class AuthMixin:

is_authenticated = False

def login(self, taken_password):

if self.password == taken_password:

self.is_authenticated = True

print(f"{self.username} is authenticated")

else:

print("Wrong password!")

def logout(self):

self.is_authenticated = False

print(f"{self.username} is loggouted")

class AbstractAdmin(ABC):

@abstractmethod

def login():

pass

@abstractmethod

def logout():

pass

@abstractmethod

def create_content():

pass

@abstractmethod

def update_content():

pass

@abstractmethod

Tout était clair ?
