💡 Hint

Common Mistakes

Using @staticmethod or @classmethod instead of @property.

Forgetting the @ symbol before the decorator.

The @property decorator is used to define a method as a property, allowing access like an attribute.

Complete the code to define a setter for the name property.

Python

class Person:
    def __init__(self, name):
        self._name = name

    @property
    def name(self):
        return self._name

    @name.[1]
    def name(self, value):
        self._name = value

💡 Hint

Common Mistakes

Using @name.getter instead of @name.setter.

Using @property again instead of @name.setter.

The setter for a property is defined using the @propertyname.setter decorator.

Fix the error in the code by completing the property getter method correctly.

Python

class Circle:
    def __init__(self, radius):
        self._radius = radius

    @property
    def radius(self):
        return self.[1]

💡 Hint

Common Mistakes

Returning self.radius causes infinite recursion.

Using incorrect variable names like Radius.

Inside the method, use the instance variable _radius with self. prefix in the return statement to access it.

Fill both blanks to create a property age with a getter and a deleter.

Python

class User:
    def __init__(self, age):
        self._age = age

    @[1]
    def age(self):
        return self._age

    @age.[2]
    def age(self):
        del self._age

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

💡 Hint

Common Mistakes

Using @age.setter instead of @age.deleter for deletion.

Forgetting to use @property for the getter.

Use @property to define the getter and @age.deleter to define the deleter for the property.

Fill all three blanks to create a property score with getter, setter, and deleter methods.

Python

class Game:
    def __init__(self, score):
        self._score = score

    @[1]
    def score(self):
        return self._score

    @score.[2]
    def score(self, value):
        self._score = value

    @score.[3]
    def score(self):
        del self._score

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

💡 Hint

Common Mistakes

Mixing up setter and deleter decorators.

Forgetting to use @property for the getter.

The property uses @property for getter, @score.setter for setter, and @score.deleter for deleter.
