Property Function in Python

When I’m using the get and set function to encapsulate the data from the user, property function was the solution to handle it.
I got the right solution with this code:

class Car:
    def __init__(self, model, year, price):
        self.__model = model 
        self.year = year 
        self.price = price

    def setmodel(self, model):
        self.__model = model
    
    def getmodel(self):
        return self.__model

    model = property(getmodel, setmodel)
    number_of_wheels = 4 

car1 = Car("BMW", 2000, 10000)
car1.model = "AAA"
print(car1.model)

In other case where I put
model = property(setmodel, getmodel) – setmodel before the getmodel – I got this error:

TypeError: getmodel() takes 1 positional argument but 2 were given

I still can’t get it why the order here give an error?

>Solution :

model = property(setmodel, getmodel)
The reason why this gives you an error is because the first param is a get and the 2nd param is the set.

property(fget, fset, fdel, doc)

fget: (Optional) Function for getting the attribute value. Default value is none.

fset: (Optional) Function for setting the attribute value. Default value is none.

fdel: (Optional) Function for deleting the attribute value. Default value is none.

doc: (Optional) A string that contains the documentation. Default value is none.
