I tried adding property decorators to my class but something went wrong.

I got 6 errors!!!

my code:

```
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):
            self.age = new_age
    def __str__ (self):
        return f"{self.name} is {self.age}"
p1 = person('moe',34)

print(person)

```
