setter issues

Hi guys, I'm having an issues with the property decorator in the browser editor. The .setter part is not acting like a decorator (all yellow text). instead it is sky blue, like a .method call. You might be seeing something I'm not. Any help would be appreciated. thanks.

product.py
class Product:
    _price = 0.0
    tax_rate = 0.12

    def __init__(self, base_price):
        self._price = base_price

    @property
    def price(self):
        return self._price + (self._price * self.tax_rate)

    @price.setter
    def price(self, new_price):
        self.price = new_price

Hi David,

Your setter is trying to set the wrong value. The variable you should be setting is _price, you are trying to set price.

Cheers
