Practice - 5 Tasks

1fill in blank

easy

Complete the code to define a class Child that inherits from Parent1 and Parent2.

Python

class Child([1]):
    pass

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

BParent1 Parent2

CParent1, Parent2

D(Parent1, Parent2)

💡 Hint

Common Mistakes

Using spaces instead of commas between parent classes.

Using square brackets instead of parentheses.

Omitting parentheses entirely.

In Python, multiple inheritance is declared by listing parent classes separated by commas inside the parentheses after the class name.

Complete the code to create an instance of Child class.

Python

obj = [1]()

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

Aparent2

Bchild

CParent1

DChild

💡 Hint

Common Mistakes

Using lowercase letters for class names.

Trying to instantiate parent classes instead of the child.

Class names are case-sensitive in Python. The class defined is Child, so the instance must be created with Child().

3fill in blank

hard

Fix the error in the class definition to correctly inherit from ParentA and ParentB.

Python

class MyClass([1]):
    pass

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

AParentA, ParentB

BParentA ParentB

C[ParentA, ParentB]

DParentA.ParentB

💡 Hint

Common Mistakes

Using spaces instead of commas.

Using square brackets or dot notation.

Multiple inheritance requires listing parent classes separated by commas inside parentheses.

4fill in blank

hard

Fill both blanks to define a class MultiChild that inherits from Base1 and Base2 and create an instance named instance.

Python

class MultiChild([1]):
    pass

instance = [2]()

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

ABase1, Base2

BMultiChild

CBase1

DBase2

Attempts:

💡 Hint

Common Mistakes

Using only one parent class in inheritance.

Trying to instantiate a parent class instead of the child.

The class inherits from both Base1 and Base2 separated by commas. The instance is created from the class MultiChild.

5fill in blank

hard

Fill all three blanks to define a class FinalChild inheriting from Alpha and Beta, create an instance obj, and call its method().

Python

class FinalChild([1]):
    def method(self):
        return "Hello"

obj = [2]()
print(obj.[3]())

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

AAlpha, Beta

BFinalChild

Cmethod

DBeta

💡 Hint

Common Mistakes

Using only one parent class.

Calling a method that does not exist.

Using wrong class or method names.

The class inherits from Alpha and Beta. The instance is created from FinalChild. The method called is 'method'.
