Complete the code to define a getter method for the attribute 'name'.

Python

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

    def get_name(self):
        return self.[1]

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

Cself._name

Dself.name

💡 Hint

Common Mistakes

Returning 'name' instead of '_name'.

Including 'self' again inside the return statement.

The getter method returns the private attribute _name using self._name. Since self. is already in the code, you need to write _name after it, so the full expression is self._name.

Complete the code to define a setter method for the attribute 'age'.

Python

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

    def set_age(self, age):
        self.[1] = age

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

💡 Hint

Common Mistakes

Assigning to 'age' instead of '_age'.

Writing 'self.self._age' by mistake.

The setter method assigns the new value to the private attribute _age. Since self. is already in the code, you need to write _age after it, so the full expression is self._age.

Fix the error in the setter method to correctly update the private attribute '_salary'.

Python

class Employee:
    def __init__(self, salary):
        self._salary = salary

    def set_salary(self, salary):
        [1] = salary

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

Aself._salary

B_salary

Csalary

Dself.salary

💡 Hint

Common Mistakes

Assigning to '_salary' without 'self.', which does not update the attribute.

Assigning to 'salary' which is just the parameter.

The setter method must assign the new value to self._salary. Without self., the assignment only creates a local variable and does not update the attribute.

Fill both blanks to create a property for 'height' with getter and setter methods.

Python

class Person:
    def __init__(self, height):
        self._height = height

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

    @height.setter
    def height(self, value):
        self.[2] = value

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

A_height

Bheight

Dheight_value

💡 Hint

Common Mistakes

Using 'height' instead of '_height' in getter or setter.

Using different names in getter and setter.

The getter returns the private attribute _height. The setter assigns the new value to the same private attribute _height. Both blanks should be filled with _height.

Fill all three blanks to create a property 'weight' with getter, setter, and a condition to allow only positive values.

Python

class Person:
    def __init__(self, weight):
        self._weight = weight

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

    @weight.setter
    def weight(self, value):
        if value [2] 0:
            self.[3] = value

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

A_weight

B>

D<

💡 Hint

Common Mistakes

Using '<' instead of '>' in the condition.

Assigning to 'weight' instead of '_weight'.

The getter returns self._weight. The setter checks if the new value is greater than zero, then assigns it to self._weight. So blanks are _weight, >, and _weight.
