Python setter TypeError: 'int' object is not callable

getter-setter, object, oop, python

Solution

I see a couple problems.

- When using a property, you do not manually call the setter's name like `an.foodsetter(1000)`. You use attribute assignment syntax, like `an.foodamt = 1000`. This is the entire point of properties: to have transparent attribute-like syntax while still having function-like behavior.

- You should be comparing `foodamount` to 100, not `self.__food`.

- a property's getter and setter should have the same name.

class Animal:
    def __init__(self,foodamount=10, location = 'Australia'):
        self.__food = foodamount
        self.location = location

    @property
    def foodamt(self):
        return self.__food

    @foodamt.setter
    def foodamt(self, foodamount):
        if foodamount >100:
            self.__food = 100
        else: self.__food = foodamount


class Tiger(Animal):
    def __init__(self,colour = 'orange'):
        super().__init__(location ='programming and gaming')
        self.colour = colour


an = Animal()
an.colour='red'
print(an.colour)
an.foodamt = 1000
print(an.foodamt)

Result:

red
100

Problem

I am trying to create a setter for my private self.__food variable. Basically i want the childclass Tiger to change the private variable which has a condition to limit the value over 100. However i receive an error : TypeError: 'int' object is not callable Where am I wrong and how can i fix this? Thanks ``` class Animal: def __init__(self,foodamount=10, location = 'Australia'): self.__food = foodamount self.location = location @property def foodamt(self): return self.__food @foodamt.setter def foodsetter(self, foodamount): if self.__food >100: self.__food = 100 else: self.__food = foodamount class Tiger(Animal): def __init__(self,colour = 'orange'): super().__init__(location ='programming and gaming') self.colour = colour an = Tiger() an.colour='red' print(an.colour) ansetfood = an.foodsetter(1000) print(ansetfood) ```
