Common Mistakes

Using the child class name inside parentheses instead of the parent class.

Forgetting to put parentheses after the class name.

The class Dog inherits from Animal to reuse its methods.

Complete the code to call the inherited method from the child class instance.

Python

💡 Hint

Common Mistakes

Using a method name that does not exist in the parent class.

Trying to call the method without parentheses.

The Cat class inherits the sound method from Animal, so calling pet.sound() works.

💡 Hint

Common Mistakes

Forgetting the opening parenthesis before the parent class name.

Using square brackets or braces instead of parentheses.

The class Car must inherit from Vehicle using parentheses: class Car(Vehicle):.

4fill in blank

hard

Fill both blanks to create a child class that overrides a method from the parent class.

Python

class Bird:
    def fly(self):
        return "Flying"

class Penguin([1]):
    def fly(self):
        return [2]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using the wrong parent class name.

Not returning a string in the overridden method.

Penguin inherits from Bird but overrides the fly method to return "Cannot fly".

5fill in blank

hard

Fill all three blanks to create a class hierarchy and call a method from the grandparent class.

Python

class LivingThing:
    def breathe(self):
        return "Breathing"

class Animal([1]):
    pass

class Dog([2]):
    def breathe(self):
        return super().[3]()

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using the wrong class names in inheritance.

Forgetting to call the method with parentheses.

Animal inherits from LivingThing. Dog inherits from Animal and calls the breathe method from the grandparent using super().
