does the @property decorator function as a getter?

Question

i am new to python and i'm trying to understand the use of the 'getter'. it's use case is not obvious to me. if i use a property decorator on a method and im able to return a certain value, what exactly would i use 'getter' for.

class Person:
    def __init__(self,name, age):
        self._name = name
        self._age = age
    
    @property
    def age(self):
        return self._age      

    
    @age.setter
    def age(self,new_age):
        if isinstance(new_age,int) and 18 < new_age < 120:
            self._age = new_age

Answer 1

The @property decorator adds a default getter on a given field in a Python class that triggers a function call upon accessing a property.

The @property decorator turns the age() method into a “getter” for a read-only attribute with the same name. If want a “setter” then add @age.setter as you did in your question.

p = Person("John", 22)
print(p.age)

Output:

22
