Challenge: Admin

Task

You have a User class from the last challenge.
The methods are corrected (User -> {self.username} in strings).
Let's define the Admin class!

  1. Define the Admin class inherited from the User class.
  2. Define the create_content() admin's method that prints the string:
    f"{self.username} creates the content".
  3. Define the update_content() admin's method that prints the string:
    f"{self.username} updates the content".
  4. Define the delete_content() admin's method that prints the string:
    f"{self.username} deletes the content".

Note

Admin has all the capabilities of User that do not need to be reimplemented. This is an example of how inheritance makes our life easier.
