Multilevel inheritance

You've gotten your hands dirty performing both single and multiple inheritance. In this exercise, you'll implement multilevel inheritance by building a new version of the Smartphone class.

To help you get started, the Computer and Tablet classes have been defined and provided below. It' important to note that Tablet inherits from the Computer class. Good luck!

class Computer:
  def __init__(self, brand):
    self.brand = brand

  def browse_internet(self):
    print(f"Using {self.brand}'s default internet browser.")

class Tablet(Computer):
  def __init__(self, brand, apps):
    Computer.__init__(self, brand)
    self.apps = apps

  def uninstall_app(self, app):
    if app in self.apps:
      self.apps.remove(app)

Istruzioni dell'esercizio

Define a Smartphone class that inherits from Tablet, call the parent constructor, and define the phone_number instance-level attribute.
Create a send_text method that shares a text message with a recipient from the Smartphone's phone_number.
Instantiate a Smartphone object called personal_phone and call its .browse_internet() method; uninstall the Weather app, and send the message Time for a new mission! to Chuck, via text.

# Create a Smartphone class that inherits from Tablet
class ____(____):
  def __init__(self, brand, apps, phone_number):
    ____.____(self, ____, ____)
    self.phone_number = ____
  
  # Create send_text to send a message to a recipient
  def ____(self, message, recipient):
    print(f"Sending {____} to {____} from {____.____}")

# Create an instance of Smartphone, call methods in each class
____ = Smartphone("Macrosung", ["Weather", "Camera"], "801-932-7629")    
personal_phone.____()
personal_phone.____("____")
personal_phone.____("____", "Chuck")
